Part of a two-story apartment building in Newark was reduced to rubble after an explosion left several people injured Friday evening.

The building, managed by Newark Housing Authority, was all but destroyed about 6 p.m. Friday after an explosion rocked the building. The cause of the blast was under investigation.

The walls of the building on South Pine Lane were blown off, leaving a refrigerator and furniture on full display.

Valery Lasky and her son work at a nearby deli.

“He said ‘Ma, a building exploded.’ I ran and looked and saw a guy climbing down the rubble. The owner of the store said there were people all over the ground,” Lasky said.

Newark officials say six people were hurt. Five were taken to area hospitals. One woman suffered from serious burns.
