A chemical spill has shut down Thompson Street from Arrowdale Road to Birrelli Road in North Haven Saturday.
The truck was traveling down Thompson Street around 8 p.m. when it lost two of the oil containers it was carrying because they were not properly secured, said police.
One of the oil containers did leak onto the roadway, according to Dennis Schain spokesperson for the Department of Environmental Protection.
The driver of the truck did not stop and police believe that the driver did not know he had lost his load.
No one was hurt and no one was evacuated, according to police.
The DEP and North Haven fire department handled cleanup.
