Hazmat crews were called when a white power that turned out to be cocaine was found at a Dallas mall Thursday night.

Dallas Fire-Rescue said the white powder was found on the second floor of NorthPark Center in front of the movie theater.

Crews at first feared the powder was from another white powder letter like those mailed across North Texas. But Dallas Fire-Rescue said it appeared someone dumped the cocaine out in front of the AMC NorthPark 15 movie theater's ticket counter.

Evacuations were not necessary, and no injuries were reported.

The cocaine was bagged up, and Dallas police took it into evidence.

Letters with white powder have been sent to hundreds of schools, banks and locations across the country, including schools and businesses in North Texas, since 2008. All of the typewritten letters have been postmarked from North Texas.

Last week, the FBI and postal inspectors announced a $150,000 reward for information about the person who has mailed the hoax letters.
