SAN FRANCISCO — A San Francisco police officer pleaded not guilty Wednesday to charges he manufactured and possessed a prohibited AR-15 style assault rifle, officials said.
Thomas Abrahamsen, 50, of Berkeley appeared in court to enter pleas on felony counts of manufacturing an assault weapon and possessing an assault weapon, according to the district attorney’s office.
An investigation into Abrahamsen began in the summer of 2015 after other members of the department tipped off officials. The probe found the officer manufactured and owned a prohibited assault rifle along with AR-15 receiver components, police said.
Abrahamsen, an 18-year veteran, surrendered Tuesday, authorities said. He was on unpaid administrative leave, police said.
The department on Wednesday could not immediately offer additional details on the case, said Officer Giselle Talkoff, a San Francisco Police Department spokeswoman.
