Police in Whitpain Township have arrested one of two men they say broke into a home in the 700 block of Danbury Drive early Saturday morning and threatened the homeowner with handguns.

In a statement released Monday afternoon, investigators identified the suspect as Brian Keith Walters, 37, of Worcester, Montgomery County, and said he was arrested in connection with the robbery, but they declined to give further details.

District Court records, however, showed that Walters was formally charged early Monday with robbery, burglary, criminal trespass, aggravated assault, reckless endangerment and terrorizing another.

He was order held in the Montgomery County prison by District Court Judge Deborah A. Lukens when he could not make $150,000 bail.

A preliminary hearing is scheduled for 10:30 a.m. Dec. 22 before Magisterial District Judge John S. Murray III.

The second suspect remains at large. Police are continuing to investigate.

The police statement said the homeowner told investigators that two black men, one wearing a ski mask, entered the house through a rear door and went to the master bedroom where the homeowner confronted them.

After a brief struggle, the statement said, the homeowner chased the two from his home.

In all, three shots were fired by the homeowner during the altercation, but it was not known whose gun was fired. The statement said no injuries were reported and nothing was missing from the home.

A K-9 team from Montgomery Township assisted at the crime scene, along with police from Upper Gwynedd, East Norriton, and the Pennsylvania State Police.
