Has Anthony Michael Hall gone Hannibal on us? Details have surfaced about his recent assault on an ex (Diana Falzone), and reportedly he bit her forehead!

The police report, obtained by Radar, says Hall "bit his girlfriend's forehead" and "pushed, shoved and spit at" her while inside of her apartment around 2 a.m. on November 10th. He returned an hour later intoxicated, when the NYPD apprehended him.

Falzone, a Sirius Radio host and columnist, had recently broken up with Hall, who suffers from bipolar disorder. While there is a restraining order against him, the site reports that he "is not under investigation in connection with the incident." And perhaps Falzone should take another look at her last column for HuffPo, tilted How Not To Date A Loser.
