Thousands of police officers from across the country joined New York’s South Asian community Thursday to mourn Didarul Islam, the NYPD officer slain in a mass shooting at a Manhattan office building earlier this week.

Mourners packed a Bronx mosque to pay respects to a New York City police officer who was among the four people killed when a gunman opened fire this week at the Manhattan skyscraper that houses the NFL's offices.
