A Warrington man is accused of slamming a door on a woman’s ankle several times, and then throwing her down the concrete steps outside his apartment. 30-year-old Christopher Cheeze of Lisa Drive is charged with felony assault and other offenses.  Court documents say the incident happened Tuesday afternoon when victim Margarita Orellana went to recover belongings from Cheeze, who is her ex-boyfriend.  She was released from Doylestown Hospital after treatment for injuries, and he has been ordered to stay away from her.  He pleaded guilty three years ago in another assault case.
