Brother-in-law of NYPD detective killed during Park Avenue massacre ‘carries on legacy’ as new police recruit

The brother-in-law of an NYPD detective killed in the line of duty vowed Wednesday to continue his heroic “legacy” of helping those in need.

Sabbir Ahmed was sworn in alongside 754 recruits at the Police Academy in Queens — almost exactly 14 months after Didarul Islam was gunned down in the horrific mass shooting on Park Avenue.

“It was my dream job to become a police officer and [I] want to [carry on] my brother-in-law’s legacy,” Ahmed, 27, told The Post after the ceremony.

Becoming a police officer had been Ahmed’s dream since he emigrated to the United States from Bangladesh when he was 14, but it was at the behest of Islam that he obtained his degree before joining the force.

Islam didn’t sugarcoat the dangers in being a cop with Ahmed, eerily foreshadowing his line-of-duty death at the hands of a crazed gunman on July 28, 2025.

A uniformed Islam, 36, was working a security detail at 345 Park Ave., in Midtown Manhattan when a Shane Tamura, 27, strolled into the lobby carrying an assault rifle and opened fire and struck him with the first fatal shot.

Tamura then killed three others before turning the gun on himself.

Islam tragically left behind his pregnant wife, who gave birth to the youngest of their three sons weeks after the massacre.

“[Islam] told me this job comes with a lot of stress, but at the end of the day you could help lots of people, whoever needs your help, and you’ll feel good about yourself,” said Ahmed.

“I want to be a great police officer and I want to serve the community and I want to help whoever needs help.”

Despite the tremendous loss, Ahmed said his parents were “really, really happy” that he was following in Islam’s footsteps.

Police Commissioner Jessica Tisch honored Islam’s memory during Wednesday morning ceremony, saying he was “killed in the line of duty last year while protecting New Yorkers.”

“Sabbir, your family has already given so much to this department as you begin your own career in the NYPD. We are especially proud to welcome you into our ranks,” Tisch said.

“Today, 755 of you raised your right hands and took the oath to serve this city. You are beginning a career that will ask an extraordinary amount of you, and one that I believe is about the noblest callings a person can take on.”
