The NYPD wants your help identifying a man they say set off several small fires in Lower Manhattan and Queens, including one on board a subway train.

A masked serial arsonist callously set a blaze next to a dozing subway passenger during a bizarre hour-long spree across Manhattan and Queens last week, police said. The firebug first lit a parked NYPD police car on fire near City Hall at around 2:20 a.

A man is wanted after he started four fires in lower Manhattan in slightly over two hours last week, and police released surveillance footage of the suspect on Wednesday to aid their investigation.
