MANORVILLE - An off-duty NYPD officer is being called a hero this morning after he helped a bus driver and an aide escape a burning bus. 

Police say the minibus went up in flames after colliding with a box truck on the LIE near exit 70 in Manorville. 

Off-duty officer Christopher Canale pulled over yesterday afternoon and saved the driver and aide who were trapped inside.

There were no children on the bus.

The aide suffered a minor injury, but no one else was hurt.
