A funeral was held Thursday for NYPD Det. Didarul Islam, one of the victims killed in Monday's shooting at a Midtown office building.

Islam came to New York City from his native Bangladesh when he was 20 years old, with "the promise of a better life," NYPD Commissioner Jessica Tisch said.

Officer Didarul Islam, killed in the Midtown shooting, was honored at a Bronx funeral and is expected to be laid to rest in Totowa, New Jersey.
