A car overturned at a roundabout.
Police have confirmed a black Toyota Yaris fell onto its roof at the junction of Black Lion Hill and Porters Park Drive, at the bottom of the hill, in Shenley.
Police were called shortly before 4.30pm.
Emergency services, including ambulances and a fire engine, were called to the scene.
The car has since been recovered and road closures have been lifted.
There were delays on all approaches into the mini-roundabout.
The 602 bus was unable to serve Shenley due to the crash and buses put on diversion.
Service Update. Due to an RTA and police closing the road at Shenleybury cottages, there will be no 602 services running in Shenley. Apologies for the inconvenience, we will keep updates coming as we hear more
