NEW YORK (AP) — The city has issued a full vacate order for a three-story Queens house after the third floor collapsed.

A spokeswoman for the city Department of Buildings says the cause of the Saturday night collapse is under investigation.

The Fire Department says a dozen people were injured when the floor fell during a party.

Two people were hospitalized, one with serious injuries. Ten people refused medical attention. One person was trapped and had to be extracted.

The buildings department says the private home was constructed in 2005. The agency said it has no records of any complaints about the house.

Far Rockaway is a remote neighborhood on a peninsula south of John F. Kennedy International Airport. It is about 23 miles southeast of Manhattan.
