The Cobble Hill teenager who collapsed and died over the weekend while fleeing a fight at a party in Prospect Park had allegedly been struck by a middle-aged man, the father of another teen involved in the melee. A friend of the late Sharif Abdallah told the Times, “They ambushed two of our friends. They came out of nowhere. They were beating on them. The father was doing most of the fighting.” Yesterday police brought in the man who says "they have it all wrong." No charges have been filed yet. The fight broke out at a going way party for a high school friend, when Abdallah was part of a group who stood up for a friend's girlfriend who another group of teens said looked like "Ugly Betty." Sharif's friends had initially claimed that he had a heart condition that may have led to his sudden death, but his family has denied that. An autopsy will be performed today.
