A man was critically injured after his car crashed into a retaining wall in Norwich early Friday morning.
Police responded to 348 W. Thames St at 12:05 a.m. on Friday after receiving several 911 called about a crash.
The car, a black 2005 Mercedes Benz CLK500, was badly damaged and members of the Great Plain Volunteer Fire Department pulled the man who was inside out of the vehicle, police said.
He was originally taken to William W. Backus Hospital in Norwich, but LifeStar transported him to Hartford Hospital.
Police said the man is in critical condition. His name has not been released.
West Thames Street traffic was diverted for more than an hour as police investigated.
Witnesses told police the vehicle might have been speeding and passing vehicles on the left while heading north on West Thames Street before hitting a stone retaining wall, police said.
Police said they expect to file criminal and motor vehicle charges against the driver of the Mercedes.
