SFPD officer arrested for allegedly possessing banned assault rifle

San Francisco Police Department says an officer was arrested on firearms charges. 50-year-old Thomas Abrahamsen, a Berkeley resident, surrendered Tuesday for alleged possession of a banned AR-15-style assault weapon and receiver components.

SFPD is said to be investigating the matter based on information gathered from other Department members. 

Abrahamsen, an 18-year veteran, was booked on one felony count of manufacture of an assault weapon and one felony count of possession of an assault weapon.

“In the spirit of the Not on My Watch initiative, Department members will continue to hold each other accountable and will act swiftly to report any behavior that might bring dishonor to the Police Department,” said Acting Chief of Police Toney Chaplin.
