Suspicious powder sent to Okla. banks

Washington_The FBI says at least a dozen more suspicious letters turned up today at financial institutions nationwide but all appear to be harmless.  The suspicious letters first began arriving Monday including at banks in the Oklahoma City metro area.

Authorities say nearly 50 letters in all with some containing a white powder have been sent to Chase Bank branches and federal regulatory offices in 11 cities. So far the letters have tested negative for poisonous or otherwise dangerous toxins and an FBI spokesman in Oklahoma City says preliminary assessments show the powder is harmless calcium. No injuries have been reported. 

JP Morgan Chase spokesman Greg Hassell says Chase branches around the country are on alert. Authorities say the letters appear to be from the same source and they're focusing on possible suspects near Amarillo, Texas, where the envelopes were postmarked.

The incident is being investigated as a first, if extreme, public backlash over the nation's financial crisis.
