Police are searching for a man who allegedly posed as a delivery person before attempting to rob a homeowner Saturday in Middletown, according to the Middletown Township Police Department.

Police said officers responded to a residence on Sidney Court following a report of an attempted robbery. Investigators said the suspect approached the home carrying a box, knocked on the door and then produced what appeared to be a handgun when the homeowner answered.

A struggle followed, during which the suspect dropped the weapon and ran away, police said. Authorities later recovered the gun and determined it was a BB pistol.

Police used drones and K-9 teams to search for the suspect, but they had not been located Saturday.

The suspect is described as a white man in his early 20s wearing a flannel shirt, blue jeans and boots. Police said he was last seen running from the area and may have left in a black sedan of unknown make and model.

Surveillance images of the suspect have been released as investigators seek the public's help identifying the person involved.
