A New York City police officer who was among the four people shot and killed by a gunman during a rampage at a Manhattan office tower will be laid to rest Thursday. Officer Didarul Islam, 36, was fatally shot Monday in a midtown building housing the National Football League’s headquarters.

Four people were killed and a fifth was injured in a mass shooting at a Midtown Manhattan office building on Monday.

Familly, friends and colleagues are preparing to mourn the NYPD officer killed in this week’s Manhattan office attack at a funeral Thursday, less than two days after hundreds stood in salute as his casket received a dignified transfer to the mosque where he’ll be remembered.
