An emaciated four-year-old boy died of a head injury after being subjected to a campaign of “incomprehensible” cruelty by his mother and stepfather, a British court heard yesterday.

He’s temporarily unconscious as I nearly drowned him

Daniel Pelka, whose physical condition was likened by a doctor to that of a concentration camp victim, is alleged to have been deliberately starved over several months.

Jurors sitting at Birmingham Crown Court heard claims that the youngster was “imprisoned” in a bedroom, which had no door handles, and force-fed salt.

Daniel, whose mother and stepfather came to Britain from Poland in 2006, was pronounced dead in the early hours of March 3 after paramedics were called to his home in Coventry.

His mother, Magdelena Luczak, and her partner, Mariusz Krezolek, both deny murdering Daniel and causing or allowing his death in March 2012. Opening the case against the couple at the start of what is expected to be an eight-week trial, prosecutor Jonas Hankin QC yesterday alleged that text messages provided compelling evidence of their guilt. In one message to her partner in February last year, which was read to the jury, Daniel’s mother is alleged to have said: “He’s temporarily unconscious as I nearly drowned him.

I am having some quiet time.” Krezolek is alleged to have told Daniel’s mother in another message sent on October 7, 2011: “Lead or take him to the room and lock him there. You will have some peace and do wait for me.” Jurors heard that Krezolek was sent another message by Luczak which read: “We will deal with (Daniel) after school. He won’t see grub at all.”

During his opening speech, Hankin said the prosecution submitted that Daniel, who was found to have suffered a subdural haematoma, was unconscious when a text message was sent from Luczak to Krezolek at 4.34pm on March 2.
