A fire heavily damaged a pizza shop in Southington early Tuesday morning.
A passerby noticed smoke coming from Townline Pizza at 1660 Meriden-Waterbury Turnpike around midnight, according to fire officials.
Firefighters found heavy fire in the kitchen area and smoke pouring from the ceiling and into other businesses in the complex.
There were no sprinklers in the pizza shop, but water from a burst hot water tank actually helped control the fire, according to fire officials.
Townline Pizza will remain closed, but the other businesses in the complex should be able to reopen, fire officials said.
The cause of the fire is under investigation.
