A Stop & Shop in Union is now closed after a fire in the underground parking garage on Sunday.

Authorities say a car fire caused heavy smoke at 1201 Stuyvesant Ave. and the building's sprinkler system to go off. No one was injured.

Union Fire Department Chief Gregory Ricciardi said repairs need to be made to the sprinklers before the building is allowed to reopen.

There was no damage to the building and minor damage to an adjacent parked car, authorities said. The cause of the fire is under investigation.
