A Leavenworth man was arrested after he allegedly knocked his girlfriend unconscious and threatened police officers with a gun, a police spokesman said.

The incident was reported at 8:07 p.m. Monday in 2100 block of Kenton Street.

Officers responded to a report of a disturbance. They found an unresponsive woman in the front yard of a residence.

“She regained consciousness,” said Maj. Dan Nicodemus, deputy chief of the Leavenworth Police Department.

The 24-year-old woman had two large lacerations on the right side of her face.

The woman’s boyfriend, a 30-year-old man, had allegedly struck her in the face several times, Nicodemus said.

Officers learned the man had gone into the residence.

“At some point, he exited the residence with a firearm,” Nicodemus said.

Nicodemus alleged that the suspect chambered a round in the handgun and made threats to the officers.

The suspect’s mother attempted to intervene, but officers held her back.

Officers eventually were able to talk the suspect into putting down the firearm.

The man was arrested for allegations of aggravated battery, aggravated assault of a law enforcement officer and a criminal threat.

The woman, who may have suffered a broken eye socket, was taken to Saint Luke’s Cushing Hospital.
