SHELTON — A driver fled after a rollover crash on Route 8 Tuesday morning, the fire department said Wednesday.

Firefighters responded to Route 8 south for a reported crash just before 10 a.m. Arriving units found a one-car rollover, with the vehicle left in the left median near Exit 13.

“The operator of the vehicle fled the scene prior to emergency units arriving,” the fire department said.

As units were on scene for the crash, the left lane of Route 8 south was closed between exits 13 and 12, causing delays in the area.

The crash remains under investigation.

Anyone with information can call the state police Troop I barracks at 203-393-4200.
