Evidence is continuing to be heard at an inquest at Sutton Coldfield town hall into the death of Mikey Powell.
Mikey died six years ago in a prison cell at Thornhill Road police station after being arrested outside his family home in Lozells, Birmingham.
Mikey’s mother shouted, “He needs an ambulance” shortly before he was taken away in a riot van, the inquest heard.
Neighbour Michael Clifford said he watched at least five police officers restraining Mikey before he was placed in a police van.
He told the inquest jury, “They were trying to calm Michael Powell down.
“He was on the ground. It sounded like he couldn’t get his breath, that he was struggling. He just kept on trying to get back up but the police officers kept him down.
“That’s when Mrs Powell made the comment about her son needing an ambulance.
“She was hysterical. She was saying he needs an ambulance not the police.”
Paramedic Peter Hemus said officers at Thornhill Road “did all they could” to save Mikey in custody.
At an earlier hearing, neighbour Minh Lee said he saw Mikey Powell being hit in the thigh by a moving police car.
