Montgomery County police have arrested a 23-year-old Gaithersburg man on rape charges stemming from an October incident during which a maid said she was attacked in a Gaithersburg Motel 6 hotel room.

Luis Manuel Rivera was taken into custody Wednesday, two weeks after a detective spotted his car and its distinctive rims on Interstate 270, police said. The car had been spotted on surveillance cameras leaving the hotel after the attack. The detective wrote down the license plate and it was traced back to Rivera.
