Security at a city park and ride site is being investigated after thieves targeted vans.

Tools have been used to gain entry into vans at the Norwich Airport Park and Ride, specifically in those marked PUK, for those using the Perenco UK helicopter terminal.

Mark Jennings, who works offshore for Petrofac, is one of the people affected.

He was shocked to notice a hole drilled into the side of his van door when he returned after a few days away for work.

"I deliberately parked my car next to some CCTV to deter something like this happening," said Mr Jennings.

"It just shows that you can take as much care as possible and it doesn't make a lot of difference."

While he doesn't think anything was taken, he has been sent CCTV images of a man walking around the area in a mask and baseball cap.

A police spokeswoman confirmed that they have been investigating three linked incidents at the Hellesdon site, all of which happened in April and May.

She said: "The first incident occurred between April 10 and April 24 in Buck Courtney Crescent when an unknown suspect(s) tried to break into a parked van.

"They were unsuccessful and nothing was stolen."

Two incidents believed to be linked to the first crime were reported from the site to police - on April 24 and May 2, in which a "quantity of tools were stolen".

Police continue to investigate the latter incident, with no arrests made.

However, the other cases have been closed "due to the inability to identify the suspects from the CCTV footage provided".

Konectbus manages the security on behalf of Norfolk County Council at the Norwich Airport Park and Ride site.
