A schoolboy was heard screaming and begging to be let inside in haunting footage filmed by a neighbour 18 months before he was found dead in a bath, a court heard.
The voice on the harrowing video - released by the CPS after it was played to a jury - is said to be that of Alfie Steele.
His mum Carla Scott, 35, and her partner Dirk Howell, 41, are on trial at Coventry Crown Court over the nine-year-old boy's death.
They both deny murder.
A distressing minute-long clip, filmed in August 2019, captures Alfie's piercing screams and finishes with him repeatedly shouting: "Let me in, let me in".
A neighbour told the court he had been locked out of the house and wasn't let back in for up to half an hour.
In a 999 call played to the jury, one neighbour said he could hear a child whimpering at the property in Droitwich, Worcs., at 5.31am on April 4, 2020.
