Police chasing stolen big rig on 5 Freeway

Los Angeles County firefighters have arrived at the scene to put out the fire before it spreads.

Traffic has backed up for miles with dozens of vehicles trapped in the gridlock.

The semi-cab has caught on fire with acres of dry brush nearby. 

Authorities detained the suspect shortly after he jumped out of the burning vehicle.

The flames quickly engulfed the cab as officers waited for the fire department to arrive. 

After several successful spike strips by the California Highway Patrol, the driver of the stolen big rig continues to plunge ahead. 

The front tire of the semi cab has blown off the truck. 

The suspect continues to drive at very slow speeds as he makes his way through the Newhall and Castaic area. 

it also appears that the front tire of the driver's side has also come off the big rig. 

The suspect wanted for stealing a big rig in Kern County continues to lead authorities on a slow pursuit through the southbound side of the 5 Freeway.

As a result, a long line of cars can be seen on Sky9 driving slowly behind police escorts and the big rig in Newhall. 

As of this moment, it appears that Kern County Sheriffs are pursuing the suspect, who has already avoided several spike strips.
