The Broward Sheriff's Office was alerted to a possible break-in at McKnight's home about 11 p.m. Friday, the South Florida Sun Sentinel reported.
When officers arrived at the scene, nothing was out of place. McKnight, 41, who was a wide receiver for the Dolphins (2001-03), and his wife, Mikki McKnight, were not home at the time of the attempted break-in.
Later, a deputy pulled over a vehicle that matched the description of a car that had been linked to a burglary in Southwest Ranches, BSO spokeswoman Dani Moschella said.
A juvenile and adult in the car could not explain why they were in the area and later admitted to being lookouts for two accomplices who were breaking into another house.
The other two accomplices -- an adult and a juvenile -- were later found hiding in a fenced yard, deputies said. The pair initially ignored deputies' orders to surrender and one was bitten on the arm by the police dog.
Deputies arrested Michael Campblin, 19, of Pembroke Pines, Christopher Diaz, 20, of Miramar, and two juveniles, ages 16 and 17, all of whom were charged with armed burglary -- a handgun was found in the vehicle -- and resisting arrest without violence.
