BROOKLYN, N.Y. - An FDNY firefighter is dead after falling nearly 60 feet off the Mill Basin Bridge in Brooklyn on Sunday night.

Fire officials say Steven Pollard, 30, of Ladder Company 170 was responding to a two-car accident with injuries around 10 p.m. on the bridge along the Belt Parkway.

NY1 is told he slipped through a gap in the bridge and fell 52 feet into a construction site below, as he crossed from the eastbound to the westbound lanes.

Pollard was with the department less than two years, and comes from a long line of firefighters.

Earlier in the day, dozens of firefighters lined the street outside the medical examiner's office in Manhattan, where Pollard's body was removed and taken to a funeral home in Marine Park.

Firefighters put up purple bunting at Ladder Company 170 in Brooklyn where Pollard worked.

"Firefighter Pollard's dad is a longtime member of the FDNY, his brother's a member of the FDNY. This is a family that's done so much for New York City and now they're going through this loss, this pain and it's a very, very tough situation," said Mayor Bill de Blasio.

"It's a very sad night for the Pollard family, for the fire department family and for the city. One and a half years on the job, Stephen Pollard was just starting out in his life tonight and the process of helping others," said FDNY Commissioner Daniel Nigro.

Fire officials say Pollard is the 1,151st FDNY member to die in the line of duty.

A full investigation is now underway.
