Twin brothers under house arrest on murder charges duct-taped a man and cut his face and toes demanding a ransom payment, authorities said.

On Friday, the U.S. Attorney’s Office for the Southern District of Florida announced 23-year-old twin brothers Devon Cooke and Donavan Cooke, of Miami Gardens, were charged with carjacking and kidnapping after they allegedly abducted and assaulted a man in an attempt to collect ransom money.

The brothers were under house house arrest on murder and attempted murder charges when the incident happened.

Authorities say on Tuesday the victim, who was not identified, drove to the twins’ home in Miami Gardens to collect money. When he arrived, the brothers assaulted him, snatched his car key and dragged him out of the car and into their house.

The brothers then bound him to a chair using duct tape and began beating him, authorities said. They used a knife to cut his face and toes and wrapped a dog leash around his neck, chocking him unconscious.
