The resident, in her 30s, who wishes to be kept anonymous, said she became aware of the alleged treats being made across Snapchat and TikTok, such as individuals planning to bring “knives and acid” to the event in Prince Charles Road on April 8.
She showed the News Shopper comments made from several users under a TikTok video posted on April 4, titled “Blackheath funfair 2025”.
One comment said, “don’t go people are bringing shanks and acid” and another one added “guys are trying to raid.”
After seeing the videos, she said that it was her duty to alert officers in hopes of increasing security at the funfair.
She added: “I was worried for the safety of families going to the fair and who work at the fair.
“I told police that I had no idea if the threats were serious or just kids trying to seem ‘hard’, but that something similar had happened in 2022 so it could be true.
“Imagine being at work and hearing that there are threats to ‘shank’ people at your workplace.”
On April 8 at around 3.30pm, officers were called to reports of a “large group of youths” causing a disorder.
Police believe that the majority of those involved had already left the scene before their arrival.
There were several arrests for separate offences, but that the exact arrest figure is unknown at this stage.
Officers arrested multiple people, including on suspicion of possessing an offensive weapon in a public place.
One person was treated for minor injuries, however, it is unknown how they sustained their injuries.
The resident said that if there had been visible police presence on the gates then the trouble would “have never started”.
She added: “The funfair had security fencing and guards who must have done a good job, if only one person had minor injuries even though the police showed up too late.
“Everyone did everything right to prevent this – except for the police.
“The only thing that could have stopped it was a strong police presence but it seems they didn’t send one.
“I’m angry with the people that caused the violence but also angry with the police for not being there to stop it in the first place when they were warned.”
A spokesperson for the Metropolitan Police confirmed that it takes all intelligence into account and a section 60 order was put into place, allowing officers to conduct stop and searches on individuals without reasonable suspicion.
It confirmed that if any disorder arises again then it may be considered to be put back into place.
In a statement issued on Facebook, organisers Capital Funfairs confirmed the event is open again — but with new safety measures including security, knife wands and CCTV.
It reads: “We are a family fun fair, for families, run by families.
“To support a family-oriented environment, children under the age of 14 will not be allowed entrance without an accompanying adult. ID may need to be shown to verify age.”
They explained that security staff have the authority to remove anyone behaving in an “unruly or abusive” manner.
The funfair has also announced it will no longer run “Mega Deal” discount days for the rest of its stay.
However, printable vouchers are available on the Capital Funfairs website, and new “Family Discount Days” are set to be announced soon.
