Police say the white powder contained in several envelopes that were mailed to various bank branches in New York City turned out to be non-toxic.
Police say seven envelopes were sent Monday to several Wells Fargo branches, a JP Morgan Chase branch and an office building. Telephone calls to Wells Fargo and JP Morgan Chase were not immediately returned.
Police say the suspicious envelopes caused evacuations of several bank branches, but no injuries were reported. Police had no suspects.
The envelopes were sent on the eve of planned May Day protests around the country.
