A fire forced the evacuation of a Manhattan apartment building on Christmas Day.

"The angel of a superintendent was banging on the door and my alarm started to go off," said one displaced tenant who lived on the Upper East Side building's fourth floor.

The blaze, which broke out shortly before noon at the building on 69th Street near 1st Avenue, grew to three alarms and spat heavy smoke into the area:


The city fire department got the flames under control shortly before 2:10 p.m.

Four firefighters were being treated for minor injuries. No residents were reported injured.

The exact number of tenants displaced is not confirmed as of this writing.

The cause of the blaze was under investigation, but officials said when firefighters arrived they found fire on the top floor of the five-story building before it extended to the cockloft. FDNY officials said heavy clutter inside an apartment complicated their efforts.

1st Avenue to York Avenue on East 69th Street was closed to traffic as cleanup continued.
