From NY1:

Fire investigators are looking into the cause of an explosion and partial collapse that injured nearly a dozen people Thursday in Chinatown.

It happened shortly before 1 p.m. inside a ground-level beauty shop located at 17 Pike Street near the Manhattan Bridge.

The fire department says at least eight people were being treated for injuries, three of which are said to be serious.

Four firefighters were also injured.

All were taken to area hospitals.

Witnesses at the scene say they first heard an explosion and felt the ground shake around the five-story walk up.

All tenants have been evacuated as a precaution.

Fire officials say the building had several violations on record.
