30 Powder-Laced Letters Sent To Banks In Seven Cities Including Dallas
Federal authorities are investigating at least 30 letters containing suspicious powder that have been sent to banks in seven cities.
The FBI said initial tests on the powder have come up negative for dangerous toxins. Additional tests are ongoing.
A law enforcement official said Tuesday the letters were mailed from South Texas to Chase bank branches in or near Chicago, Cincinnati, Dallas, Denver, Newark, New Jersey, Oklahoma City and Washington.
Postal inspector JoJan Henderson says the letters appear to be related and appear to be from the same source.
The official, who spoke on condition of anonymity, says the letters began showing up at the banks on Monday.
The official spoke on condition of anonymity because he was not authorized to discuss the matter publicly.
An FBI spokesman in Oklahoma says the letters sent there indicated the threat was ``based on past actions of the bank.''
