A TEENAGE mother, who has admitted being part of a drunken attack on a cyclist left in a bloodied heap, has three previous convictions for assault, Southampton Crown Court heard.

Stephanie Hill, 19, had been drinking when she attacked a middle-aged stranger, who she struck on the head and pushed, and who ended up in a river.

On another occasion she had twice kicked a police officer when she resisted police entering a flat and on the other she attacked a man in a row over drink when she feared he was going to call the police on his mobile phone.

The convictions emerged as the prosecution closed its case against Hill, who they claim was with three men who had beaten up innocent cyclist David Baker in a passageway at the Central Bridge when it was undergoing repairs.

Hill, of Lydgate Green, Southampton, has admitted common assault but denies the more serious allegations of causing grievous bodily harm with intent and grievous bodily harm. She also pleaded not guilty to stealing alcohol from the Co-op.

John Smith, 27, of Tamella Road, has admitted causing grievous bodily harm with intent.

The teenager said they had been drinking and the men had taken crack cocaine before they went to the shop to get beer. She remained outside because she didn’t want to get involved in what they were doing, The court has heard how at the bridge one of the men punched Mr Baker, who had been coming in the opposite direction. As he tried to get up he was punched again and Hill admitted kicking him once in the head.

She told the court: “I don’t know why. I don’t know whether he was bleeding. I didn’t kick him very hard. I don’t know what effect it had on him.”

Hill then described how Mr Baker was then kicked, punched and stamped on.

“Nobody was saying anything.

I didn’t encourage them.

There was a lot of blood. It happened so quick.”

Under cross-examination, she said: “As I walked away from the bridge I felt scared and sick.” She then admitted her father had kicked her out of his house because she had been “out of control”.

Hil said she had wanted to call an ambulance but didn’t.

“Johnny told me to leave and I left”.

Jurors are expected to retire today to consider their verdict.
