Police say they have arrested a Portland man for harassing the families of victims of the mass shooting in Aurora, Colo., last July.

Kevin Purfield is accused of emailing, calling and using social media to contact the victims' relatives. Investigators say the communications weren't threatening, but were annoying and included "vile language."

Aurora police contacted Portland officers in late February and asked them to help with the investigation of the 45-year-old.

Portland police said Wednesday they arrested him without incident. He was booked into the Multnomah County Jail for investigation of telephonic harassment and stalking, both misdemeanors.

Bail was set at $10,000. Purfield is due to be arraigned Thursday. It was not immediately clear if he had a lawyer.

The movie-theater shooting left 12 people dead and 70 injured.
