A grandma who is standing up to nuisance quad-bikers on a Bradford estate claims that her cars have now been targeted in an acid attack.

Defiant Elaine Booth, 52, said yesterday’s attack in a lay-by outside her house on Broadstone Way, Holme Wood, has only made her more determined to fight her corner.

Last month she told the Telegraph & Argus about nuisance quad and off-road bikers that were plaguing Holme Wood. She approached the T&A after one drove at her and her two-year-old grandson.

She was threatened and called a ‘grass’ in the aftermath of the story.

Police said her Land Rover Discovery and her husband’s Mitsubishi Space Wagon were sprayed with acid at 2.15am yesterday.

Officers have released a CCTV image (pictured) of a man they want to speak to in connection with the incident. Mrs Booth said: “We don’t regret standing up to them – this has just made us more adamant, to be honest.”

The Mitsubishi also had its rear and side windows smashed on Tuesday, she said.

Mrs Booth also said “two lads” in a black Volkswagen Golf had been pipping its horn at her and shaking their heads, while another youth allegedly shouted from a car: “Do you like your car, you grass.”

Sgt Adam Crisp, of the Tong and Wyke neighbourhood policing team, said: “This has caused a considerable amount of damage to the vehicles which will likely cost hundreds of pounds to repair.”

Any witnesses should call PC Andrew Gordon on (01274) 376512, or Crimestoppers on 0800 555 111.
