Officials are investigating a white powder found in an envelope sent to Cox Communications in Tulsa.
A Cox employee opened the letter Wednesday morning and alerted officials. Tulsa Fire's Haz Mat and Tulsa Police bomb squads were called to the offices at 11500 East 51st Street.
There is no word yet on what the powder is, but so far it does not appear hazardous. The employee who opened the envelope has not become ill or reported any problems.
There was no return address on the envelope.
