A 35-year-old Silver Spring man was charged with raping his former girlfriend, Montgomery County police said.

The woman agreed to meet her ex-boyfriend Saturday morning at his apartment in the 9300 block of Piney Branch Road, where police said the man physically assaulted and raped her. The woman was able to get help from a nearby resident who called 9-1-1. Police arrested Roberto Samayoa-Pineda outside the apartment and charged him with rape. He was being held Monday without bond.
