YOUTHS raced through a shopping centre, intimidating shoppers and swearing at security staff.

Police say the incident happened in St St Helens Lagrange Arcade, Church Square Shopping Centre on Wednesday.

Police Community Support Officers were also abused.

But police warned the youngsters they face a knock on the door because their faces have been caught on police body cameras.

In a statement police said: “To the cherubs (and parents by proxy) who felt it appropriate to ride their bikes within the La Grange shopping arcade, intimidating shoppers, swearing at security staff and abusing our PCSO's - we have you on bodycam, we have your names - we shall see you soon. #KnockKnock #ASB.”

The Star has reported previously on concerns of shoppers and businesses about bike riders roaring through pedestrianised areas.

They have also raised fears someone would get knocked down.

However, these would appear to be the first public reports of bike riders tearing through an indoor shopping centre.
