A Connecticut man is wanted on attempted murder and other charges, after police say he fired shots at an off-duty police officer early Thursday on I-270, Maryland State police said.

No one was injured in the incident, which police said began when an off-duty Prince George’s County police sergeant saw an Audi with Connecticut plates that was speeding, driving erratically and with the lights off on the CapitalBeltway near Georgia Avenue about 2:30 a.m.

The sergeant called state police from his private vehicle, and followed the Audi onto northbound I-270. The officer then saw someone in the fleeing car firing shots at him, police said.

The officer continued to follow the Audi from I-270 onto the exit for Route 121, back to the highway. The car then went onto Father Hurley Blvd., and back to an on-ramp for I-270, where the Audi stopped and another shot was fired at the officer.

No one was hit by the gunfire. State and county police responded to the area, but could not find the Audi and the off-duty officer lost sight of the car near Hyattstown, officials said.

State police investigators traced the license plates and notified Connecticut authorities, who set up surveillance and arrested the man in New Haven on Thursday afternoon. State police obtained an arrest warrant charging Hill with attempted second-degree murder, reckless endangerment and first-degree assault.
