Two women and a teenage girl this evening pleaded not guilty to extortion of €15,300 from a man in three separate incidents.

Police sources said that the women - a mother, her daughter and her sister, - who cannot be named by court order - had allegedly blackmailed a man whom they photographed naked and about to have sex.

The sources said one of the women allegedly owed a street vendor €600. When he demanded payment, it was agreed that they would have sex and the matter would be forgotten.

The woman arranged for the other two to be in the same room and to photograph the man when he got naked. They allegedly took photos using a mobile phone and a camera.

The woman is then alleged to have showed the man the photo taken on the mobile phone and demanded cash in return for destroying the phone. Cash was handed over and the phone was destroyed.

A few days later the woman demanded and got more cash in exchange for a photograph taken using the ordinary camera.

However after the three women turned up at the man's home with another photo and demanded more cash the police were informed.

A total of €15,300 were allegedly handed over before the man revealed everything to the police.

The incidents allegedly took place over the past two months.

The two women were each granted bail against a personal guarantee of €2000 while the girl, aged 17, was granted bail against a guarantee of €1,000.
