This is the horrific moment a sobbing four-year-old girl watches a gang pistol whip her father and then threaten to kill her.

The shocking footage from a home security system shows four armed thugs as they beat a businessman senseless while his daughter begged them to stop.

Recorded on CCTV, the thugs battered the dad on the kitchen floor as they forced him to tell where the family’s valuables were at the home in Philadelphia, Pennsylvania State, USA, on Monday, 6th November.

Then his daughter bravely stepped forward to tell the masked gunmen to stop.

But, the dad said later, one of them turned to her and snarled: “Shut up or I [will] kill you too.”

Earlier the gunman had frogmarched the homeowner and his cousin into the house from the garden where they clubbed them to the ground and tied them up.

Later footage shot in the raid shows the thugs fleeing with a safe containing jewellery and guns before escaping in a black getaway car.

The girl’s father told local media of his daughter’s terror saying: “She’s scared, she cries. They threatened to kill her.

“She makes a lot of noise, and they talk to her, ‘Shut up or I [will] kill you too.’

“When they talked to my daughter like that, oh my God, I wanted to die too.”

Terrified, the girl fled and hid behind a sofa until the gunmen had gone.

Her dad added: “My wife, she cries every night. She can’t sleep. She can’t sleep.

“They know we have a business because they asked, ‘Where’s the money, where’s the money?’

“I said, ‘I don’t have money.’ They said ‘Yeah, you have money here.'”

Philadelphia Police Department said in a statement obtained by Newsflash: “The complainant reported the offenders took his safe, firearms, and jewelry before fleeing westbound on 66th Ave.”

The police are appealing to the public for information that could lead them to the suspects.
