Staffordshire Police and Fire and Rescue Service are urging people in Cannock to stay away from the Orbital Retail Park after a car crashed into a gas sub-station.
The collision, which involved a red BMW 3 series, happened around 7.10 this evening near the Sainsbury's petrol station.
A 300-metre exclusion zone has been set up around the area after gas was found to be leaking from the sub-station. People working nearby have also evacuated.
Gas engineers are on-site assessing the damage. Officers have arrested a man from the Brownhills area in connection with the incident.
CCTV footage shows the pair steal from a couple in broad daylight.
