Newly released video shows Mark Anthony Conditt, the Texas man who terrorized the city of Austin for weeks in March, detonating an explosive device as SWAT vehicles surrounded him on a highway.

The video, from March 21, was released by the Texas Department of Safety.

Conditt, 23, can be seeing weaving his truck through the streets of Round Rock, Texas, attempting to avoid the several SWAT vehicles pursuing him.

As Conditt pulls out of a parking space, the DPS helicopter pilots radio his movements to their colleagues on the ground.

"Air to ground, he's on the move," one pilot says.

Once Conditt nears Interstate 35, he is boxed in by two white SWAT vans and stops after he is rammed from behind.

As SWAT teams begin to surround him, an explosion takes place within the truck.

The video was made public during a meeting of Texas DPS commissioners, ABC Austin affiliate KVUE reported.

The 19-day bombing scare ultimately killed two people and injured four.
