Police raid transport company for truck explosion
Police have swooped on the transport company responsible for the M5 truck explosion that sparked traffic chaos across western Sydney.
Officers have spent the morning raiding Owens Transport at Banksmeadow in the city's south after one of the company's vehicles shut down the motorway on Wednesday.
The truck was heading west on the M5 at Kingsgrove at around 11am when the driver clipped a barrier and spilled highly flammable diesel for 400m.
The fuel ignited and triggered five explosions before flames engulfed the heavy vehicle, sending thick plumes of toxic smoke into the air.
The truck was carrying rice crackers and instant noodles, with fire fighters getting inside the container to extinguish the blaze.
The explosion brought traffic on the motorway to a stansdtill, causing major traffic delays well into the evening.
As part of this morning's raid, police along with officers from the Roads and Maritime Services inspected all of the company's vehicles for maintenance and compliance.
9NEWS understands the truck driver has been speaking to police, with CCTV from near the scene also being investigated.
More to come.
