Horrifying video shows brutal attack on black woman by Pittsburgh pizzeria manager

On Friday night, a Pittsburgh woman was brutally attacked by a restaurant manager for refusing to leave the premises of Milano Pizza.

Video posted on Facebook showed Jade Martin and a man identified as the Milano's manager locked in disagreement. The manager ordered Martin to leave the premises, but she refused to comply.

Rather than attempt to de-escalate and summon police, the man brutally backed Martin into a corner and pummeled her with his fists, bellowing, "I said 'please!'" over and over as he slams her backward into a table, then banged her head against the floor.

The Coalition for the Safety of Black Women and Girls has called for an investigation.

On Saturday night, protests formed outside the restaurant, where temperatures hovered at a chilly 15 degrees F Saturday evening and are expected to drop to 2 degrees overnight.
