Harrisburg city spokesman Matthew Coulter said a Domino's delivery worker told police he thought he was being targeted for a robbery after he arrived at his destination and saw people "lurking in the shadows," The Patriot-News, a Harrisburg newspaper, reported Thursday.

Coulter said a call came in for a delivery at the same address the following night, and a police officer posed as a delivery worker by placing a Domino's placard on an unmarked car. The spokesman said a teenage boy pointed a pellet gun at the officer after he arrived, but fled with four others when the officer identified himself. The undercover officer, along with a second officer hiding in his back seat and other police in the area, chased down the suspects

Police arrested four 15-year-old boys and a 14-year-old boy on charges of robbery and conspiracy to commit robbery.
