A school has hit out at a group of selfish bikers who wrecked an end-of-year prom, forcing teachers to call the police.
Pupils at St Gregory's Catholic Academy, in Longton, Staffordshire, were left in tears' after around 60 people on motorbikes 'blocked' the road and revved their engines at the kids.
Parents say the teens were left 'intimidated and frightened' at what was supposed to be a celebration of their time at the school.
