Police in Mount Lebanon and state police in a helicopter were unable to find a burglar who was interrupted in the act of robbing a Shady Drive home last night and escaped by jumping off a second-story deck.

Officers don't know if the incident is connected to three other residential burglaries in Mount Lebanon last week.

In the latest one, police said a man came home to his apartment in the 700 block of Shady Drive East about 7:10 p.m. Wednesday and caught a glimpse of a man dressed in dark clothing when he opened his door.

The suspect ran out through a sliding glass door in the rear and onto a deck from which he jumped. Police said he entered the apartment throught that door, which was unlocked.

The resident was unable to provide a good description.

Two other residences were burglarized on Friday and another the previous Tuesday. In all three cases, police said, the burglar entered through unlocked doors.
