A hero cop who received the Medal of Valor for his role in disarming the Times Square bomb in 2010 has died at the age of 45.

Gregg Abbate suffered a heart attack Thursday at home after falling ill at Tobay Beach on Long Island, where he was working as a lifeguard, said his former boss, Sgt. John Ryan.

Abbate, of Massapequa, was one of three technicians who rendered safe the bomb Faisal Shahzad left in an SUV parked in Times Square in May 2010.

“He’s the one you wanted next to you when things were getting rough,” said Ryan.
