Philadelphia police are looking for a bandit who was dressed like postal worker during a home invasion robbery in Olney.

According to police, the robber approached a 44-year-old man putting a baby into a car on the 5400 block of North 2nd Street about 3:15 p.m. Wednesday, pulled a gun from his mailbag and forced the victim back into his home.

Inside the house, the robber dressed in the U.S. Postal Service uniform was joined by three accomplices, police said.

During his 15-minute ordeal, the victim was bound by zip ties and duct tape and pistol whipped while the robbers ransacked the house looking for money, police said. The infant, who was left in the car during the heist, was not harmed.

The robbers took $5,000,  an iPhone 7 and the victim's house and car keys before fleeing in two vehicles. The victim declined medical treatment.

Police have released surveillance video in an effort to identify the suspects.
