The body of fallen NYPD Officer Didarul Islam was transferred from the Manhattan medical examiner's office to a mosque in the Bronx on Tuesday. Islam was fatally shot at an office building in Midtown Manhattan on Monday.

But on Monday evening, Islam, who was regularly assigned to the 47th Precinct in the Bronx, was gunned down by an armed suspect identified as Shane Tamura, as the officer was dong a paid detail shift at 34d Park Avenue, a skyscraper home to several large New York City corporations.

The father of hero NYPD cop Didarul Islam grew so distraught when he learned of his son’s death at the hands of a deranged gunman in Midtown Manhattan that he suffered a stroke, his family told The Post.

Police say a gunman who killed four people in a Manhattan skyscraper before taking his own life claimed to have a brain disease linked to contact sports and was trying to target the National Football League’s headquarters in the building.

The New York Yankees held "a moment of silence in memoriam of NYPD Officer Didarul Islam" before Tuesday's game. The 36-year-old served on the force four years.

The alleged gunman at a shooting rampage in a midtown Manhattan office building was identified as 27-year-old Shane Tamura, of Nevada.

The “dignified transfer” is a New York Police Department rite. Its choreography honors those who died for their fellow citizens.
