Police Scotland confirmed that officers attended the event and provided advice as parents with crying children raged about the £35 (€40) ticket price.

The event, organised by House of Illuminati, was eventually called off mid-way through, the BBC reports.

One attendee said: “It was basically advertised as this big massive Willy Wonka experience with optical illusions and big chocolate fountains and sweets. But when we got there, it was practically an abandoned, empty warehouse, with hardly anything in it.”

House of Illuminati has promised to refund disappointed parents and posted a screenshot on Facebook suggesting it has issued 850 refunds.
