(Reuters) - An armed suspect was holding an unknown number of hostages inside an eastern Pennsylvania volunteer firehouse on Tuesday, officials said.

Reports of an armed suspect at the LaMott Fire Company in Cheltenham Township, about 13 miles north of Philadelphia, came in to authorities at about 10:40 a.m., said John Corcoran, spokesman for the Montgomery County Department of Public Safety.
