Roads around Cannock's Orbital Retail Park, including the main A460 route, were closed for nearly six hours on Sunday evening after a car crashed into a gas sub-station.
The collision, which involved a red BMW 3 Series happened at around 7.10pm near the Sainsbury's petrol station.
The impact led to a gas leak from the sub-station and police and fire crews set up a 300 metre exclusion zone to ensure the safety of the public. This also meant evacuating staff from the business park.
No-one was injured in the collision but officers have arrested a Brownhills man, believed to be the driver of the vehicle, who made off from the scene. He is currently being questioned by officers at a local police station. Anyone with any information is urged to call Staffordshire Police on 101.
Gas engineers worked through the evening to repair the damage, and the roads were reopened at 12.40am today.
