Jimmy bled to death after being attacked at a bakery store
A man accused of murdering 16-year-old schoolboy Jimmy Mizen had admitted hitting a girl in 2005 in a row over £20, the Old Bailey has heard.
Jake Fahri, 19, from Lee, south-east London, is accused of throwing a glass tray at Jimmy at a bakery in Lee last May, severing an artery in his neck.
Mr Fahri slapped and kicked 16-year-old Ellis Harrington because the £20 he owed her had been repaid by his mother.
The accused, who had also hit Jimmy's older brother in 2003, denies murder.
Jimmy bled to death on 10 May 2008 after being attacked at the Three Cooks bakery store with his brother Harry.
Mr Fahri admitted throwing the tray at Jimmy but said he had done it in self-defence and did not intend to hurt the schoolboy.
Zoe Johnson, for prosecution, said: "The defendant approached Miss Harrington, poked her in the head, pushed her head back and said 'Who you looking at?".
"When she said she wasn't looking at him, he spat into her face.
"He grabbed her jacket and slapped her in the face several times.
"The defendant kicked Miss Harrington's legs from beneath her and she fell, hitting her back and head."
Mr Fahri admitted the assault on Miss Harrington and received a supervision order and was ordered to pay £50 compensation, the court heard.
'Grassed' the accused
Mr Fahri had hit Harry Mizen in 2003, when he was at school, after his mother complained to the school about Mr Fahri bothering her son, the jury heard.
Miss Johnson said: "The defendant had seen Harry Mizen in the street and believed that Harry Mizen had 'grassed' him to his school."
Mr Fahri justified it to the police claiming Harry had called him names.
During the trial the court heard how the accused and the brothers got into a fight when Mr Fahri punched Harry Mizen.
The trial also heard from Surgeon Professor Jonathan Shepherd who said that a shard of glass had shot into Jimmy's throat horizontally and gone in 1.6in (4cm) and the impact was such that pieces of the glass tray was found 6ft (1.8m) above the ground.
The trial continues.
