NEW YORK - Authorities say a novelty grenade was to blame for an evacuation at a building near New York's ground zero.<br />
<br />
The police bomb squad was called to 2 World Financial Center in Lower Manhattan at midday Thursday when a security guard reported a package that seemed suspicious.<br />
<br />
The NYPD declared the situation all clear about 90 minutes later.<br />
<br />
Brookfield Properties, which runs the property, ordered an evacuation as a precaution.<br />
<br />
The building is near the World Trade Center site. A 1993 bombing there killed six people and injured more than 1,000. The Sept. 11, 2001, attacks killed nearly 3,000 people.
