**Please be aware of minor language in the clip** This was the terrifying moment a boy racer lost control of his souped-up fiesta at an unauthorised car cruise - and mowed down a crowd of spectators. Witnesses say the the young driver was trying to wow spectators by pulling off a huge wheel spin - or 'burn out' - at a B&Q car park. But horrifying mobile phone footage shows his Ford suddenly shooting forward and veering off the makeshift drag strip - ploughing into spectators and injuring 17. Teenager Megan Whitlock, 16, was left left drenched in blood and rushed to hospital with cuts and bruises to her face. The youngster said she remembers crashing into the windscreen but little else about the accident in Plymouth, Devon.
