A father could have been under the influence of a cocktail of drugs when he fatally shook his 10-week-old daughter, a court heard.

Darren Turner, 32, from Thamesmead, allegedly caused a fatal head injury to Mya-May Turner in November 2016.

Blood tests later showed he had amphetamines, cocaine, morphine and cannabis in his system.

Prosecutor Sarah Whitehouse QC said: "He could have been suffering from the effects of all of them at the relevant time, apart from cannabis."

Turner allegedly assaulted his daughter while her mother was out, on November 4 2016, the Old Bailey heard.

A neighbour allegedly heard loud music and a male voice shouting, around the time Mya-May allegedly suffered her fatal injuries, between 2.30pm and 3pm.

Mya-May's mother, Danielle Cox, had texted Turner to say she was on a bus heading towards Woolwich, the court heard.

Mrs Whitehouse said Turner took Mya-May to Queen Elizabeth Hospital in London just before 4pm.

She had suffered a "severe head injury" and she died six days later.

Mrs Whitehouse said Turner told medical staff that he had fed Mya-May and put her into a bouncy chair, where she fell asleep.

Later on, he noticed she was not breathing and was unresponsive, he had said.

Pathologist Nathaniel Cary carried out a post-mortem examination which found the baby had been "subjected to a forceful gripping of her chest" around the time she suffered a head injury, jurors heard.

Mrs Whitehouse said: "It was that head injury which ultimately proved to be fatal."

She added: "He concluded this is the sort of pattern of injuries seen when an infant is forcibly squashed, shaken and thrown down on to soft furnishing."

Mya-May had suffered rib fractures typical of "squeezing of the chest", the court heard.

Several of them were said to have happened shortly before her death and others several weeks before, the court heard.

Turner, who also has a child by another woman, has denied manslaughter and child cruelty.
