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.
StokeOnTrentLive report that parents have been left furious by Thursday's events as the youngsters' party was crashed.
The bikers were escorting a pupil whose mum claimed had been a victim of bullying at the primary school.
But after the girl was dropped off, the riders are said to have remained outside the school gates.
But this has been denied by the bikers who say they did not blockade the road - and claim they were themselves verbally abused by parents.
The clash happened at around 6pm as year 6 pupils were arriving for their prom.
Many parents say they were left unable to drive down the road due to a 'blockade', and those children that did make it through had to be 'carried out of their limos by teachers'.
A Facebook event was set up calling for 'as many bikes as possible' to escort the girl to the school.
Pictures and video from Thursday evening show a group of bikers waiting before driving in the direction of St Gregory's.
Vikki Smith, aged 32, whose son attended last night's prom, said: "My son was stuck in his limo with eight other children as they couldn't get through the road. You couldn't see for bikes, it was swarming. I asked them to move and they completely ignored me.
"We were trying to take pictures of our children, but they were revving their engines so loud, the kids were absolutely petrified. My kids were dragged out of the limo by teachers for their own safety.
"One child got stuck in the middle and was that scared he had to be carried into school crying, shaking and screaming. The teachers were trying to get them inside school as quickly as possible. Five parents rang 999.
"We've got no issue with the bikers bringing a child to the prom, but why couldn't they let everybody else through? They were intimidated and frightened."
Adele Forbes' daughter also attended last night's prom. The 47-year-old said: "They blocked the road and my daughter was late for the prom because of it. They told us they'd been told to escort a girl who is being bullied at the school.
"The mum of this child had started to get agitated at an awards evening on Tuesday night telling people to 'f***k off'. She was saying she was going to kick off then.
"A lot of our children are not used to that kind of behaviour and don't deserve it. They want to remember their last few days at St Gregory's as a happy place, a safe place.
"But the only thing they're going to remember now is someone being aggressive on the playground and they won't understand why."
The cavalcade was organised by two friends after the girl's mum issued a social media appeal. They raised £400 which paid for the girl's dress, hair and make-up.
Organiser Clare Campbell said: "There were a lot of bikes and when we got there, bikes were pulling up along the road and making way for traffic, parents got impatient and a large man started to shout, swear and threaten bikers.
"I was threatened in front of my children. I told them all to stop. Their behaviour is what was upsetting the children not the bikes.
"I’m very happy that none of the bikers retaliated to the abuse we got. All we wanted to do was make a little girl's night special and have her arrive in style. Bikers are great people and we do a lot for charity.
"I have arranged numerous biker escorts to proms and never had an issue. In fact everyone has loved it. I’m truly saddened and shocked at last night's behaviour towards the bikers. Under no circumstances did we attempt to block the road.
"I feel bad for the poor children that had to witness the disgusting behaviour of the parents. We tried to do something nice and are now wrongly criticised for it.
"The bikers would have left a lot sooner if all the parents hadn't made such a scene. We weren’t wanted there and they were ready for trouble. It was totally disgusting."
The mother of the child has declined to comment.
