Philadelphia police are investigating a home invasion in Olney involving a suspect police say was dressed in a U.S. Postal Service uniform.

The incident happened Wednesday around 3:15 p.m. on the 5400 block of North 2nd Street.

44-year-old Kahamphoy Detmongkhone stood on his front porch with a gun in his pocket Thursday, still shaken from a home invasion robbery where the suspects threatened to harm his 9-month-old son.

"You tell me where the money is. I'm gonna bring your son in here--kill him, torture him, kill him," Detmongkhone described the terrifying moments.

It started with the victim carrying his infant out to his car. He was approached by what appears to be a postal worker in uniform, carrying a bag, according to police.

"The impersonator, impersonating the postal worker, grabbed the male, brandishing a gun," Northwest Detectives Captain Malachi Jones said.


Police say the gunman forced the victim, a professional poker player, back into his house with the baby still in the car.

"The baby in the car the whole time. They were in the house 30 or 40 minutes," the victim said.

"They ransacked the house --took money, keys, car keys and a cellphone," Captain Jones said.

According to police, the gunman was joined by three other suspects. They took more than $5,000 in cash and an iPhone.The suspects were caught on camera fleeing the home. All the while, the child was still inside the car.

"God's on my side," the victim said.

Surveillance cameras also caught the four suspects escaping in two vehicles. A dark colored Buick Lucerne and a Pontiac Grand Prix.

As for the robber in the postal uniform; "We don't believe that it is a mailman who committed this robbery. He is dressed in a U.S. Postal uniform--jacket, pants and even a bucket type hat," Captain Jones said.

"Money, couple thousand ain't nothing. I want my son's life--only son I have," Detmongkhone said.

The suspects have been described as four black males ranging in high from 5'5" to 6'0". The suspect wearing a postal uniform was described as 5'5" with a muscular build, in his mid-20s, wearing dark sunglasses.
