Miami-Dade police have arrested two teenagers suspected of attacking a man in a motorized wheelchair for his necklace. The disturbing attack was caught on surveillance video.

Celedono Carrera, 66, was pulled from his chair and beaten in his own driveway at Ward Towers on 54th Street and NW 22nd Avenue. The public housing building is home for a number of senior citizens.

Seventeen-year-old Royce Simmons and 13-year-old Xavier Hyland will be charged with strong-arm robbery and battery on an elder.

Carrera was headed home after visiting a friend at the University of Miami hospital. He stepped on the Metrorail and noticed a group of thugs. According to Carrera, "It was a gang that runs through there. They dedicate themselves to robbing the elderly. They get on, and they watch and they signal each other. I noticed them, but I didn't pay any attention."

When Carrera got off at his stop on 54th Street, he noticed two men following him. "Since there were a lot of people in the streets, they weren't going to rob me in the streets, but when I came inside they came inside and they weren't going to miss the opportunity to rob me," said Carrera.

The first man dragged Carrera from his wheelchair; all the while, he fought back. "I gave him a punch right here. And cut him here. And I fought with him. And then he went to pull here and he took my big medallion that I had."

Prize in hand, the thug backed off just as another one moved in for Carrera's wallet. Thankfully, Carrera's neighbors stepped in and stopped this outrageous attack. "The people came out of the building and started screaming and they left," said Carrera.
