A bomb scare Tuesday at the blood bank in Westbury turned out to be a false alarm, Nassau police said.

After receiving an initial call from the city, police bomb squad officers investigated a threat made Tuesday at the New York Blood Center offices on Prospect Avenue in Westbury. Nassau County police said a 911 call at 10:30 a.m. reported the threat, placed in an earlier phone call to the center.

Bomb squad officers and a bomb-sniffing dog were sent to the offices, located near the intersection with Elizabeth Street, the building was avacuated and Prospect Avenue was closed in the immediate vicinity of the center's offices.

The center is part of the Long Island Blood Services network, which has served Long Island and Queens for more than 40 years, according to its website. The center provides blood products and services to about 50 hospitals throughout Nassau, Suffolk and Queens, its site says.
