Ahmed Mohammed went on the run after fleeing Birmingham Crown Court before he could be sentenced.
The brazen 19-year-old even returned for his coat before running away for a second time. He surrendered to police the following day and was sentenced to a total of 16 months behind bars.
James Bruce, defending, told Recorder Keith Raynor: “He left to go and make arrangements and say his goodbyes. He had a bank card he wanted to give to his mother.”
Balvinder Bhatti, prosecuting, said Mohammed bit his 18-year-old victim in Phillips Street Park, Newtown, on June 9 last year. She said: “He stood in front of her and started grabbing at her phone. She pulled away and there was a struggle.
Eventually he leaved forward and bit her hand, she released the phone and the defendant was able to run off.”
The girl was left with bite marks on her hand and had to take antibiotics for two weeks after the attack, the court heard. But Mohammed was nailed by police who made a DNA match from saliva on his victim’s hand.
