Texas police are on high alert amid new threats from biker gangs.

A bulletin issued by the Texas Department of Public Safety warns that the Bandidos biker gang may be planning to target high-ranking officers and their families.

The bulletin says that Bandidos members in the military are supplying the gang with explosives, and that the gang is planning to detonate car bombs.

These attacks would be in retaliation against police for shooting “their brothers” in last weekend’s Waco shootout.

CNN reported:

The gang has ordered a hit against Texas troopers and other officers, according to the bulletin. Among the threats are running over officers at traffic stops and the use of grenades and Molotov cocktails and firearms.

The bulletin includes some locations as possible targets: McLennan County Jail in Waco as well as sites in Austin, El Paso, Dallas, Corpus Christi and Houston.

The Texas Department of Public Safety didn't immediately respond to CNN's request for comment.
