MEDFORD, Ore. -- Two brothers who run a security business are facing criminal charges.

Jason Lee Libby, 29, and Donald Eugene Libby, 29, own and operate Jackson County Security.

On Jan. 7, Jason was at the Weldon Cleaners no Crater Lake Avenue. He is contracted to provide security services to the business.

While there, he contacted a 40-year-old male, according to a press release from the Medford Police. At the time he was wearing a black uniform, badge, duty-belt equipped with a firearm, baton and various other tools. He was driving a dark blue Ford Crown Victoria with no markings.

Police say Jason put the man in handcuffs for trespass after Jason determined the man was not there to do laundry.

A video shows Jason shoving the man after he had been put in handcuffs, the press release said.

As this was happening, a 54-year-old woman entered the business and told the handcuffed man that Jason was not a police officer, according to the release.

At this time, Jason attempted to arrest the woman for trespass. Police allege that Jason pushed the female against his vehicle and used a wrist lock on her. This caused her pain.

Police say the man in handcuffs attempted to leave the scene. Jason then chased him down and used force to bring him back to the store.

Medford Police arrived on scene shortly thereafter.

The case was presented to a Jackson County grand jury who indicted Jason on assault and harassment charges.

Medford Police say a second incident involving Donald happened on Jan. 8 around 11:13 p.m.

A Medford Police officer was patrolling an area in east Medford when he saw Donald near Camina Drive and Veneto Circle.

At the time, Donald was driving a black Crown Victoria with a spotlight, according to the press release. He was wearing an uniform similar to a police officer and appeared to being giving a field sobriety test to a driver a stopped vehicle.

During their investigation, police learned that that Donald stopped the vehicle by standing in front of it and shinning a flashlight in the window and ordering the driver to stop.

The 18-year-old driver thought it was a police officer and stopped, according to the press release.

Donald allegedly questioned the driver and his passenger; police say he had the driver step out of the car and performed some limited field sobriety tests.

Police say he told the driver he could be arrested for DUII and trespass. At this time, a Medford Police officer arrived on scene.

Police say the security company is not contracted to patrol this particular area and Donald made the stop on a public roadway.

Donald's case was also heard by a grand jury, that indicted him on two counts of criminal impersonation.
