Andrea Proto, 19, of North Haven, was charged with third-degree assault and disorderly conduct shortly before 2 a.m. Wednesday after police said she bit her boyfriend at his North Benson Road home.

The boyfriend had grabbed Proto's phone to check her text messages, police said, and when he refused to give it back, she attempted to wrest it from him. In the process, police said, she bit his arm and scratched the back of his neck.

She was released on a promise to appear Wednesday in Bridgeport Superior Court.
