ARMSTRONG COUNTY, Pa. - Police said they arrested a man accused of holding his ex-girlfriend hostage for several hours Thursday.

Investigators said 37-year-old Keith Kammerdeiner sprayed the victim with mace and bound her hands and legs during the incident.

Police said the victim let Kammerdeiner inside her home in Worthington Thursday morning but when she asked him to leave he refused and held her against her will.

"They were former boyfriend girlfriend. They broke up several months ago. She has moved on from him and he apparently does not want to," said Trooper Brian Wolfe.

Police said Kammerdiener threatened to kill the 27-year-old with a homemade explosive device and sexually assaulted her.

Officers said the woman was later able to escape and call 911 from a nearby store after several hours.

State troopers said they surrounded the woman's home but Kammerdeiner had already left.  He was later found at a Pittsburgh T station by Port Authority Police. Kammerdeiner was taken to UPMC Mercy Hospital to be checked out and then was taken into police custody.

"They thought he was under the influence of some narcotic. They weren't sure. He also had bleeding on the face from a knife wound," Wolfe said.

The victim was taken to a nearby hospital to be treated for minor injuries. She is expected to be OK.

Kammerdiener faces several charges including rape, aggravated assault and making terroristic threats.
