A number of young people have been running into a South Lakes supermarket and screaming.
Believed to be part of a TikTok craze, South Lakes Police said it had been going on for several weeks.
Yesterday, Booths in Ulverston was the latest supermarket to be targeted, officers said.
South Lakes Police added: “They are causing a nuisance to staff and customers.
“We have CCTV footage of those involved and will also be making enquiries with Ulverston Victoria High School.
“Please make sure you know what your teens are up to of an evening.”
