A mass brawl broke out at a family funfair after ‘teenagers armed with knives started attacking each other’, it’s reported.
Witnesses claimed parents and their children ‘ran screaming’ in fear for their lives as the groups began attacking each other during the event billed as ‘Blackpool Comes to Oldham’.
Detectives say they are now investigating the fracas at the funfair last night – after police sent riot vans and children were reportedly left "traumatised".
One woman complained to the fair’s bosses on Facebook: “There were police everywhere, people screaming and running.”
It’s understood some youths were kicked out by security, and the fair in Hollinwood was forced to shut early, reports the Manchester Evening News .
Officers say that, as it stands, there have been no reported injuries or arrests.
They said that although weapons were reportedly seen, it has not been confirmed if any were used.
The violence erupted on ‘Bring a Friend Thursday’, a promotion where ‘you pay and your friend rides free’.
A statement on the official Blackpool Comes To Oldham Facebook page apologised for ‘rowdy youths’ and said that security will be stepped up as a result of the incident.
They said: “We would like to apologise to anyone whose enjoyment was disturbed by some rowdy youths at tonight’s hugely popular Bring a Friend promotion.
“There were no reported injuries and no first aid was required.
“However, we would like to reassure everyone security will be stepped up, to prevent access to anyone trying to disrupt people’s fun.”
A spokesman for Greater Manchester Police said: “We were called just after 8.15pm to reports of a large scale violent disorder involving mainly youths.
“There were also reports that weapons had been seen but it has not been confirmed if any were used.
“There have been no reported injuries or arrests at this time. Enquiries are ongoing.”
A witness, who took his young daughter to the fair on Thursday night and rang police when the fight broke out, told the M.E.N that ‘youths piled in and it completely kicked off’.
He added: “There were riot vans here. My daughter is only three. We were absolutely traumatised.”
Dozens of people also posted on the Blackpool Comes to Oldham Facebook page.
One woman wrote: “Was a good evening till all the teenagers gathered was absolute ridiculous the amount seen many gangs tryna fight but lucky mine and my friends kids didn’t see what ever had gone on cause security asked us to leave just as we realised something’s wrong there a load of selfish t***ts many were girls also ruined a fun night for kids.”
Another posted: “My son was there and he said it was awful. There were police everywhere, people screaming and running and everyone escorted off the fair early.”
A third added: “Good night ruined by idiots, kids were gutted it shut early xx.”
Another visitor wrote: “Not being funny I had to pay full price even though I was wiv my mate and I got in cued up for twenty minutes got on a ride and then had to be escorted out by police.”
However, there was some praise for how staff handled the situation when it ‘kicked off’, with one follower commenting: “Security did a fantastic job for how many was on and how many kicked off wow.”
