Courtroom security had to leap into action on Friday when the brother-in-law of entrepreneur Hugo Chetcuti lunged at the man accused of killing him.

“What are you laughing at?” Noel Falzon snarled as he tried to approach Bojan Cmelik, before being restrained by court security and dragged out of the courtroom.

Mr Falzon lost his temper after spotting the accused allegedly smirking – something lawyer Joe Giglio, appearing parte civile on behalf of the Chetcuti family, said he had also noticed.

Magistrate Marse Ann Farrugia gave Mr Cmelik a stern telling off. But with an angry Mr Falzon still fuming outside, she was forced to pospone the sitting to November 7.

Earlier in the hearing, the court heard how Mr Cmelik was born with the surname ‘Mitic’. He had only become ‘Bojan Cmelik’ in March 2016, less than three months before he entered Malta.

Mr Cmelik was no stranger to crime, with police in Belgrade telling their Maltese counterparts that he had a history of robbery, counterfeiting and committing slight bodily harm.

A police constable recounted how officers had found Mr Cmelik’s Serbian passport and driving licence at an apartment he shared with his brother Adam. Although the two lived together in Pieta’, they were not on speaking terms and would go out of their way to avoid each other.

JobsPlus had no record of him whatsoever, an official from the government agency told the court.

The case continues on November 7.

3.46pm What a heated hearing. The magistrate was left with little option but to put off proceedings, and the tensions have now spilled out into the law courts' corridors.

That's all from this live blog, thank you for following events with us. Check back shortly for a summary of the sitting. 

3.43pm The fireworks continue outside the courtroom, where Mr Falzon continues his invective against the murder accused, swearing at him as he is led away in handcuffs - and surrounded by security officers. 

3.40pm Confirmation - the case is adjourned to November 7. 

3.35pm The magistrate has put off the sitting to another day. Tempers flared, security had to get involved and tensions were just too high to continue proceedings on this occasion.

3.27pm It looks like Dr Giglio might be right: angry voices can be heard outside the courtroom. 

Magistrate Marse Ann Farrugia tells Dr Giglio that she could have charged Mr Falzon with contempt of court but did not do so because she understood it was a difficult situation. 

It's a tense environment inside the courtroom: three security guards are standing up, at the ready, as angry voices can be heard outside. 

3.23pm The magistrate asks Mr Cmelik to stand up and admonishes him. 

"You are accused of a very serious crime, one of the most serious," she tells him. "There's nothing to laugh about". 

Mr Cmelik tries to get a word in but is quickly told to be quiet. 

"If you don't behave, I'll continue proceedings without you. Is that clear?" 

"Clear," Mr Cmelik mumbles back. 

The magistrate asks if Mr Falzon can continue testifying, but Dr Giglio is not convinced. He says that it is unlikely that Mr Falzon will have calmed down so quickly. 

3.20pm The magistrate adjourns Mr Falzon's testimony and says she did not notice the accused smiling. 

Lawyer Joe Giglio tells the magistrate that it is not the first time Mr Cmelik/Milic has smiled during proceedings. 

"There's always a smirk on his face, but I never brought it up to avoid kicking up a fuss," he says. 

Dr Giglio notes that Mr Checuti's family is under strain. "Everyone has feelings here," he says. 

3.18pm Chaos in the courtroom. Mr Falzon is physically restrained and taken out of the courtroom after lunging at the accused, who he accused of laughing as he was testifying. 

"Why are you laughing you piece of...." he raged before it all kicked off. 

3.15pm Hugo Chetcuti's brother-in-law, Noel Falzon, takes the witness stand. Mr Falzon served as operations manager in six of Mr Chetcuti's establishments over the past six years. 

Mr Falzon tells the court that he got to know Adam Mitic back in May 2016. 

"He was a very good bartender," he recalls. 

3.14pm Mr Saliba tells the court that when he ran a search for Mr Cmelik, he drew a blank - there were no records at all. "There was nothing I could print," he explains. 

3.11pm Inspector Mifsud is done testifying. Next up is Joseph Saliba, a senior executive at JobsPlus. 

3.06pm The accused was not always known as Bojan Cmelik, the court is told. In the past, his name was Bojan Mitic. 

On July 23, Maltese police received confirmation from Belgrade confirming that the accused was born with the surname 'Mitic'. He changed it to Cmelik on March 13, 2016. 

On July 24, Maltese police asked for information about Mr Mitic's criminal record. But this time, they were told that that information had to be sent by letters rogatory - an official request made by the courts. 

3.05pm Yet another inspector takes the witness stand - Robinson Mifsud. Inspector Mifsud tells the court that the police asked Interpol for any background information they might have on Mr Cmelik on July 15. 

That same day, they were informed that Mr Cmelik had a record of robbery, counterfeiting documents and causing slight bodily harm.

3.03pm Inspector Sammut says that it is not unusual for people deported from Malta to go to court in their home nation, pay a small fee and apply to change their name.

3pm Inspector Frankie Sammut is next to testify. Inspector Sammut works in the police's immigration section, and he tells the court that Mr Cmelik arrived in Malta on June 1, 2016. 

2.58pm Although the brothers lived together, it was not an idyllic arrangement. When one entered the kitchen, the other would move to another room. They did their best to avoid each other.

2.55pm Reminder: in an earlier sitting, the court had been told that the Cmelik brothers shared an apartment for a while but were not on speaking terms. 

2.49pm Bojan Cmelik's brother lived in Malta, a police constable tells the court. PC Briffa recalls how on July 7 - the day after Mr Chetcuti was stabbed - he was instructed to go to Tower Road in Sliema to meet Mr Cmelik's brother, Adam, who lived in Pieta'. 

PC Briffa was one of the officers who subsequently searched Adam's apartment. There they found Bojan Cmelik's Serbian passport and driving licence and a phone inside a bedside table. 

On the night of the stabbing, PC Briffa was stationed at Mater Dei, keeping guard as Mr Chetcuti received medical treatment. 

2.47pm The inspector tells the court that she was with IT expert Martin Bajada when he retrieved CCTV footage from the scene of the crime. Inspector Butters steps off the witness stand. 

2.45pm Inspector Butters goes over events on the night of the murder. She was at Sliema police station when the incident was reported - the office of a fellow inspector, Jonathan Ransley, had been forced open and she was working on that case, she tells the court. 

2.43pm Inspector Lara Butters will be the first person to testify this afternoon. 

2.36pm People are gradually entering the courtroom. Mr Cmelik is in the room, as is his lawyer Ishmael Psaila. The accused is wearing a bulletproof vest beneath his jacket, as he has on previous occasions. Mr Chetcuti's brother Isaac was also spotted outside. 

2.32pm Good afternoon, and welcome to this live blog. We'll be following events as the compilation of evidence against Mr Cmelik continues. 

Three pieces of information which have emerged from previous sittings are listed below. Click the links to find out more. 

• Mr Chetcuti's bowels were pierced in the stabbing, with that leading to an infection which ultimately killed him
• Mr Cmelik was apprehended after an hour-long chase on the night of the stabbing, and had to be tasered three times before he stopped resisting arrest. A knife was tucked into his waistband. 
• DNA of three separate people was found on the murder weapon, a knife: Mr Cmelik's, Mr Chetcuti's, and a third person's.
