Boy racers who have been causing disruption across Norwich for years have turned to blocking city roads in order to hold illegal races on them.

It comes after a councillor reported two suped-up cars pulling out in front of her while she was trying to take a shortcut through the Vulcan Road industrial estate on the way back from a meeting last week, blocking her off and allowing two supercars to pull out and speed off.

The incident is the latest in a line of incidents of anti-social driving in and around the city, particularly in Britannia Road, which has prompted Norwich City Council to implement a Public Space Protection Order (PSPO) effectively banning boy racers from city streets.

Conservative Broadland district councillor for Hellesdon, Lacey Douglass, said she was shocked by the incident - which even involved a Ferrari.

She said: "Two parked cars just pulled out in front of me and I had to stop, they completely blocked me off and then drove off up the road.

"Then when I got to the end of the road I saw this Ferrari suddenly in front of me along with another very smart car.

"I was so shocked, I don't think you'll ever be able to stop it.

"I think we need better education along with a lot of other things."

Inspector Will Drummond from Norfolk police's roads and armed policing team, said the force had launched operation Octane to address the latest issue of large groups of cars going on sprees of anti-social driving.

He also said the incidents had been taking place in Caister-On-Sea, where roundabouts on a motorway had been blocked off to form a race track.

He said: “We have found incidents of roundabouts being blocked either side of a section of carriageway - that’s not acceptable, it’s putting themselves in danger and others in the process.”
