"She walked into the lobby and was carrying a Dunkin' Donuts box, walked up to the window, when the officer greeted her asked if he could help here she said 'I'm here to feed the pigs,'" Framingham police Lt. Harry Wareham said.

McNamara then allegedly reached into the box and began throwing raw bacon and sausage at the officer and smearing the greasy meat onto the bulletproof glass.

"It's clear she may need help," Wareham said.
