A suspicious white, powdery substance delivered in the mail yesterday to the office of U.S. Sen. Pat Toomey, R-Pa., in a Center City skyscraper – sparking a homeland security and hazmat scare – turned out to be cornstarch, police said.
An intern opened a letter containing the powder in Toomey’s office, on the 17th floor of 8 Penn Center, said Officer Tanya Little, a police spokeswoman.
Department of Homeland Security, fire and hazmat officials were on the scene at 17th Street and JFK Boulevard to investigate about 3 p.m. About an hour later, they determined that the substance was harmless, Little said.
