A World Financial Center building across the street from the World Trade Center was evacuated Thursday because of a suspicious package that turned out to contain a toy grenade, police said.

Police said a private security guard noticed the package during a screening at 2 World Financial Center, a 44-story building with 2.7 million square feet of office space.

The item turned out to be a novelty grenade, police said. Officials said people would be let back into the building.

The World Financial Center is home to major financial institutions including Merrill Lynch, Deloitte and OppenheimerFunds Inc.

The complex is made up of four glass and copper-crowned towers and encompasses more than eight million square feet of office space.
