The teenager, who can not be named since he is a minor, and a friend were sitting on a bench playing guitar when two men armed with knives approached them.
The men demanded their cellphones and wallets. The teenager just recently got a new cellphone from his mother, so he told them he did not have one.
One of the suspects then searched him and found the cellphone in his jacket pocket. When the boy tried to grab the knife, a part of the blade broke off. He tried to flee, but the suspect caught up to him and stabbed him in the head.
According to the boy he did not realise he had been stabbed. Only when his friend told him he was bleeding badly, he realised what had happened.
