Police said the man broke through the access arm at the front gate of state police headquarters in Bridgeport on Thursday, drove his pickup into an open garage door and then crashed into a vehicle lift.
The suspect was arrested when he attempted to flee. Troopers said they learned later that Bridgeport police were searching for the vehicle, which had been involved in accidents earlier in the day.
No injuries were reported in any of the accidents.
The man told authorities he was being chased, but there was no evidence to back that claim, police said.
