The fire was in an “extremely dense” part of Prospect Park on a hill, and there were no structures nearby to be threatened, an FDNY official said.

Firefighters extinguished a second brush fire in Prospect Park on Saturday, roughly a mile away from the site of Friday night’s larger blaze City Fire Department officials said. Forty smoke eaters responded to a fire near the LeFrak Center at Lakeside ice skating rink at about 2:40 p.

On Friday night, flames could be seen piercing through trees in the 526-acre New York City park in the middle of the borough.
