A yoga class was cut short after a member of the public called the police to report a “mass killing” after seeing several people lying on the floor. Participants in the class, which was being held at the Seascape cafe, inside the North Sea observatory in Chapel St Leonards, Skegness, Lincolnshire, were in the midst of meditation when officers turned up on Wednesday night. In a Facebook post, the cafe said someone had “reported a mass killing” after seeing people on the floor inside the building. They wrote: “If anyone heard the mass of police sirens in Chapel St Leonards at 9.30pm last night then please be reassured … “They were on their way to the observatory after someone had reported a mass killing in our building, having seen several people laying on the floor … which actually turned out to be the yoga class in meditation. “Thank you to Lincolnshire police for their prompt response. I can’t imagine for one moment what would have being going through their minds on the way.” The cafe regularly plays host to yoga classes in the evenings. The Facebook post added: “We are not part of any mad cult or crazy clubs. “All in all, this situation turned out positive and we are of course grateful.” The North Sea observatory has large, triangular windows that face the sea. A Facebook post on the cafe’s page says the venue holds New Moon yoga classes on Wednesdays from 7.30-9pm where you can feel “called to dive deep into the lunar cycle”. Pictures in the post show yoga mats next to the window. Lincolnshire police confirmed to the PA news agency that the call was made at 8.56pm “with good intentions”. A spokesperson said in a statement to PA: “A call was made following concerns for the occupants of the North Sea observatory, at Chapel St Leonards. “Officers attended, we’re happy to report everyone was safe and well.”
