Police are looking for a clumsy troublemaker who allegedly attempted to set fire to a local tavern this past Mother’s Day, but accidentally set his cohort ablaze, say witnesses.

NYPD units from the 52nd Precinct and members of FDNY’s Battalion 15 responded to a report of a fire at the Woodlawn Café at 3700 Bainbridge Ave., by the Woodlawn Cemetery train stop at 9 p.m. on May 8.

NYPD spokeswoman Arlene Muñoz said police were looking for the “unknown person who started a fire intentionally to an occupied building… and the case is being investigated by the Fire Marshal.”

Witnesses, who continued to celebrate Mother’s Day at the neighborhood bar/restaurant despite the incident, reported that the older suspect had been drinking when his younger pal, the alleged arsonist, attempted to have a drink. He was immediately denied service and was tossed from the bar for prior incidents. One bartender reported, “He used to steal the tips off the bar.”

“He was very aggressive,” reported one witness who was shocked when she saw the flash of fire ignite outside the bar. She recalled the blaze “nearly knocked me off my feet.”

Joseph Pagan Sanchez, 46, an employee of Gary & Gino’s Pizza next door, said the suspect duo drove around the corner in a truck and pulled over at the back of the bar at 3100 Jerome Ave., and saw one of them toss what appeared to be a bag. “[W]hen I turned around, he lit a match and it ignited,” said Sanchez. “It sparked fire up the side of the building. The entire building was in flames.”

But the arsonist turned his partner into a victim, according to Sanchez. “The old guy got burned,” he continued. “It looked like he got gasoline on his arm and his legs and arms were on fire.” Sanchez helped knock out the fire. “This is freaking crazy,” said Sanchez, gazing at the charred sidewalk. “My boss just paid $40,000 for the new sidewalk.”

The unidentified suspect eventually was free of the flames, before jumping back into the truck and fleeing the scene.

Neither the NYPD or FDNY have reported an arrest in the case, but investigators reportedly have video of the incident and know the identity of at least one suspect.
