San Francisco Officer Arrested on Suspicion of Assembling Illegal Rifle
Abrahamsen, 50, is accused of violating a state law against assembling an assault rifle or weapon capable of firing a large .50-caliber BMG bullet.

Officer Thomas Abrahamsen of the San Francisco Police Department has been charged with weapons violation for allegedly assembling a .50 caliber AR-style rifle.
A San Francisco police officer has been arrested on suspicion of assembling his own illegal AR-15-style assault rifle, officials announced Wednesday.
Officer Thomas Abrahamsen, an 18-year veteran of the department, surrendered to authorities Tuesday and was booked and will face two felony weapons charges, San Francisco police said in a statement.
Abrahamsen, 50, is accused of violating a state law against assembling an assault rifle or weapon capable of firing a large .50-caliber BMG bullet.
Under a law approved by Gov. Jerry Brown on July 1, rifles with a “bullet button” that allows for a clip to be dropped with the press of a button and quickly replaced were banned. The law Abrahamsen was charged with violating would include an AR-15-style rifle modified with a bullet button or any weapon that fired the large BMG bullet.
