PORTLAND, Ore. (AP) — Authorities arrested a Portland man accused of placing a pen camera in a co-worker's office to obtain video of her using a breast pump.

Police spokesman Sgt. Pete Simpson said Tuesday that Russell Kent Gordon was fired Jan. 15, the day after the woman discovered the camera on her desk and alerted supervisors.

The 44-year-old information technology employee was arrested Friday on charges of burglary and invasion of privacy. He was booked into the Multnomah County jail and released on his own recognizance.

Simpson says detectives are not aware of any additional victims.
