OKLAHOMA CITY - Authorities are investigating after a suspicious envelope was delivered to the Better Business Bureau Tuesday afternoon.
Around 12:30 p.m., emergency crews were called to the BBB to investigate an envelope with a white powder in it.
Hazmat crews and firefighters responded to the call to investigate.
Fortunately, officials deemed the envelope safe after determining the substance was just talcum powder.
It is similar to another suspicious envelope that was delivered to the BBB last month.
Drivers are encouraged to avoid the area.
