Last rites for NYPD Detective and Air National Guardsman Joseph Lemm — who was killed by a Taliban bomber in Afghanistan last week — will be held at St. Patrick’s Cathedral in Manhattan, the NYPD announced Sunday.

The funeral Mass is scheduled for Wednesday at the cathedral at Fifth Avenue and 51st Street. The viewing is set for Tuesday at St. Anthony of Padua at 85 Harrison St. in West Harrison in Westchester County.

Lemm was one of six US troops killed when a Taliban bomber targeted an American-Afghan patrol Dec. 21. He also served as a member of the NYPD’s Bronx Warrant Squad.
