Another arson attack on a seemingly random car has put worried folk living in a city estate on red alert.

During the early hours of Saturday morning, Denise Hunt was woken by neighbours as her partner's VW Passat Estate was on fire.

It comes less than two weeks after a similar incident in George Winter Court in Catton Grove, just a 10-minute walk away, when on May 1 a Nissan Juke was seen on fire in the middle of the night.

CCTV footage shows, once again, someone lighting a bag underneath the car before leaving it to go up in flames.

Mrs Hunt, 58, said: "It happened around 12.55am on Saturday and was my other half's car. 

"We were both asleep and it was a neighbour who banged on our door in the middle of the night when the fire was in full flow.

"When the fire brigade arrived they thought at first it could've been a mechanical fault but when I checked our CCTV to see when it started, I was shocked to see that someone had done it on purpose.

"They have taken rubbish out of my neighbour's bin, set fire to it and placed it under the car - waiting a couple of minutes for it to catch fire - before walking away.

"Neither me or my other half has slept since it happened.

"We heard about the incident which happened in George Winter Court as well, so I hope the person responsible gets caught before it happens again."
