An FDNY dog found traces of accelerant on three gloves inside the car of a Queens landlord whose apartment house burned down in a suspicious fire that killed three people, police sources told The Post.
Cops and fire investigators were searching the home and Toyota 4Runner of Eric Chen in Flushing late Tuesday, when the canine made the discovery, the sources said.
Police seized the SUV, as well as digital recording equipment, a computer monitor and a hard drive, the sources said.
No arrests have been made in the case and no charges have been brought.
Chen, 29, purchased the home at 90-31 48th Ave. in February, and had since tried evict eight tenants who remained in the house.
Building department records show that as many as 60 people may have lived in the home at one point — one of 26 open violations at the three-family Elmhurst home.
Most of the violations occurred before Chen bought the property, records show.
Surveillance footage also showed an unidentified man entering the house and leaving shortly before the flames broke out, killing three people inside.
Witnesses and sources said two men died behind a locked second-floor door and the third on the third floor of the house.
Sources initially believed the blaze was an electrical fire.
Chen did not return a call for comment Wednesday.
He repeatedly declined to comment to The Post on Sunday and Monday.
