(Nick Wagner/Austin American-Statesman via AP) (CNN) — Newly released video from a Texas law enforcement helicopter shows the explosion that ended the life of Austin serial bomber Mark Conditt as pursuing officers tried to arrest him earlier this year. The video, released by the Texas Department of Public Safety, shows just how close several officers were to being injured when the homemade bomb went off the morning of March 21. Conditt was driving his SUV around 2 a.m. CT as tactical teams followed him near Round Rock, just north of Austin. The video eventually shows one police van in front of the bomber’s vehicle when another bumps it from behind. The SUV glances off the van in front and slides into the median between an access road and the highway. An officer sprints up to the front passenger door and swings three times in an attempt to break the window. Another officer begins to take a potential shooting stance near the right rear of the SUV. The imaging in the black-and-white video shows an explosion in the driver’s seat area that sends debris to the left, out into the road. What looks like a piece of metal flaps from the door area. “Got an explosion. Got an explosion inside the vehicle,” an officer, apparently in an air unit, says. Officials said no officers were seriously injured. Conditt, 23, was responsible for making seven devices, killing two people and wounding several others in Austin and near San Antonio over nearly three weeks. The series of bombs led to the deaths of two African-Americans and injured several others, including a Latina, raising fears of possible hate crimes. Police later labeled the attacks domestic terrorism. The video was shown Friday morning at an open meeting of the Texas Department of Public Safety commissioners.

The bomber's vehicle exploded while surrounded by SWAT cars, video shows. 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. One SWAT officer who was within feet of the truck was blown back from the blast. 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. Three packages were detonated at residences in Austin, while another explosive was triggered by a tripwire and a fifth went off at a FedEx distribution center about 65 miles southwest of Austin, according to authorities. A sixth package was found intact at a different FedEx center, and the seventh exploded in Conditt's car with him inside. ABC News' Jack Date and Bill Hutchinson contributed to this report.
