Cumia is alleged to have attacked his girlfriend

(CNN) Anthony Cumia, once half of the shock-jock radio team known as "Opie and Anthony," was arrested Saturday on charges of abuse after allegedly attacking his girlfriend in his New York-area home.

Danielle Brand, 26, says she suffered a broken rib in the alleged altercation, which took place in Roslyn Heights, Long Island.

Brand told police that Cumia, 54, pinned her against a wall and strangled her when she attempted to flee after the pair argued. She said Cumia stomped on her hand, injuring it.
