Two men who beat a college student to death with his own bicycle lock had just been on the losing end of a fight and were looking for someone to pick on, the victim's brother said.

Tombol Malik, a 23-year-old University of Illinois at Chicago student, and his best friend encountered the men while leaving a party at a housing complex several blocks from campus early Saturday.

Malik and 23-year-old Anthony Popelka had asked Muaz Haffer and Mantas Matulis, who was bleeding from his ear, if they needed help, prosecutors said Sunday.

"They were just looking for somebody easy to pick on," said 31-year-old Sati Malik, Tombol's brother.

Witnesses told investigators that Haffer first hit Malik with his hands, then took Malik's bike lock and started beating him on the head with it. After Malik fell to the ground, Haffer continued to beat him with the bike lock, prosecutors said.
