CNN — As many as 10 people are believed to be trapped in the rubble of a building that collapsed Wednesday morning in Philadelphia, city Fire Commissioner Lloyd Ayers said, according to CNN affiliate WPVI.
The building collapsed at the corner of 22nd and Market streets in Philadelphia's Center City area, WPVI reported
The Occupational Safety and Health Administration has been told it was an accident at a demolition site, and it has investigators on the way, representative Leni Fortson said.
A witness, Jordan McLaughlin, told CNN affiliate KYW, that a building "collapsed the wrong way and landed on a thrift shop" that had people inside.
McLaughlin said he and others rushed to help people out of the rubble. He said he helped two people out, and saw up to five others escape within the first 10 minutes.
The fire department was called to the site at 10:43 a.m., Capt. Jeffrey Thompson told CNN. Thompson said it wasn't immediately clear whether it was an apartment building or an adjacent building scheduled for demolition.
Video from WPVI showed two people helping a third person, apparently hurt, away from the rubble. It also showed emergency personnel walking on and around rubble on an exposed area of a ground floor
