A mentally ill man has been detained indefinitely after killing a father-to-be by stamping on his head in an east London hospital.

A court at the Old Bailey heard that paranoid schizophrenic, Kamran Uzzaman, originally from Bangladesh, was being treated at Mile End Hospital when he got into a fight and was transferred to another ward.

It was here he met his victim, 31-year-old Prodip Debnath, who was also originally from Bangladesh.

Mr Debnath was being treated for poor mental health, including depression.

On April 7th2010, two days before the killing, Uzzaman was seen bending Mr Debnath’s thumbs back and kicking him in the head.

Mr Debnath, who was due to have a baby girl, told staff that Uzzaman was “very dangerous.”

The next day, 20-year-old Uzzaman became “aggressive and rude” towards Mr Debnath’s sister when she asked him why he hurt her brother.

On April 9, staff decided there should be checks on Uzzaman every 15 minutes.

Mr Phillip Bennetts, QC, who was prosecuting, told the court that during the evening he appeared “restless” and was seen “waving his arms in the arms in the air and laughing to himself.”

A member of staff checked on Mr Debnath at 7.25pm and he was well. She later noticed Uzzaman going into his room and saw him leaving at 7.45pm.

Mr Debnath was found in his room covered in a blanket after being stamped upon on the side of his head.

Attempts were made to revive him but he died soon afterwards at the Royal London Hospital.

Uzzaman appeared on videolink from Broadmoor Hospital. He was described by Psychiatrist Dr Darryl Gregory as “one of the most mentally unwell patients I have ever seen.”

After the killing, Uzzaman said he had been “talking to God and the prophet” and that he had “killed the devil”.

He pleaded guilty to manslaughter on the grounds of diminished responsibility and the court imposed an order under the Mental Heath Act without limit of time.
