Butler Township police Sunday night arrested a teenager they say attacked his girlfriend with a hammer, breaking her forearm and causing facial and other injuries, during an alleged assault at a motel where the couple had been staying.

The defendant, 19-year-old Damien M. Large, is also accused of hitting the victim with his hand, which knocked out two of her teeth, police said. The 33-year-old victim was treated for a number of injuries at Butler Memorial Hospital.

District Judge Kevin O'Donnell arraigned Large on felony charges of aggravated assault and aggravated assault with a deadly weapon, and misdemeanor charges of terroristic threats, reckless endangerment, simple assault and strangulation.

He was placed in the Butler County Prison on $50,000 bond following arraignment.

Police said they were called around 8:30 p.m. for a reported assault at the Super 8 motel on Route 8 south. Officers found Large on the second floor. They also learned that he was wanted on a bench warrant.

Officers searched him, police said, and turned up a claw hammer that was concealed down the front of his pants.

The victim was found in the third-floor room that she and the suspect had been staying at for some time, according to investigators.

She accused Large of assaulting her and threatening to kill her during the past week, charging documents said. The woman told police that the defendant was angry because he believed she was cheating on him.

The alleged assaults, she recounted, occurred on different days. In one instance, documents said, Large hit her on the face so hard with his open right, that it dislodged two upper left teeth.

The suspect also punched her in the face and on both arms, documents said, and choked her “numerous times” with both of his hands on her throat, “causing her to (lose) consciousness.”

Additionally, the woman told police that Large hit her with a claw hammer on the left side of her head, the upper left leg and buttocks and the left arm.

She recalled that the defendant at one point swung the hammer toward her head, police said, and she raised her left forearm to block the hammer.

“The hammer (struck her forearm (and) caused a fracture to her ulna bone,” documents said.

Police described her other injuries as being a hemorrhage in the left eye, and “heavy bruising” on her upper leg, both arms, face, upper back, waist and buttocks.

The woman was taken to the hospital for medical treatment. Her condition was not known Monday.

Large's preliminary hearing is scheduled for Jan. 14. Online court records did not indicate if he has an attorney.
