Officers at the precinct then took Bradley into custody based on the allegations of a 19-year-old man involved in the road rage incident who had reported the confrontation earlier, Murphy said.
He also was charged in connection with a May 4 incident in Port Jefferson Station, where Murphy said Bradley approached police officers at a robbery crime scene, identified himself as an Immigration and Customs Enforcement Officer and offered his assistance. In the Sunday incident, the teenager told investigators that he and Bradley got into a dispute while in their vehicles at about noon Sunday near Woodhull Avenue and Route 347 in Port Jefferson.
"One guy was making a turn, and one guy cut the other off," Murphy said. "I guess there were horns blown and whatever . . . hand gestures."
Bradley made a U-turn, put on his emergency lights and pulled the teenager over, police said. Bradley was wearing a bulletproof vest, a badge and carrying what appeared to be a holstered gun, the man told investigators. Bradley identified himself as an Immigration and Customs Enforcement officer, Murphy said.
The teen was handcuffed, and taken in Bradley's vehicle to Bradley's home at 163 Grove St., police said. The teen was later taken back to his car and released. The teenager was relieved, Murphy said, probably thinking, " 'Oh wow, I got a break!' But he eventually spoke to his father."
He and his father reported the incident that evening. Murphy said Bradley filed a complaint Monday.
Bradley's version of events were not available. Bradley, charged with unlawful imprisonment and two counts of criminal impersonation, was to be arraigned Wednesday in First District Court in Central Islip.
Police asked anyone with information to call 631-854-8626.
