Crowds of revelers on the UK’s hottest day flocked to Richmond Falls, where officers seized several large sound systems and large canisters of nitrous oxide, known as laughing gas, which is sometimes used to get high. They also removed 200 bottles of beer, cider, vodka and other spirits on Tuesday. Some local residents were concerned about anti-social behavior linked to the hot weather, according to North Yorkshire Police. The force said it broke up five men from Middlesbrough for anti-social behavior and arrested a youth from County Durham on suspicion of assault after a disturbance. Inspector Martin Metcalfe said: “Residents rightly do not want their town to be used as an Ibiza nightclub and we are doing something about it. “As temperatures soared into the 30s yesterday and hundreds gathered in Richmond Falls, my team and I took action to prevent crime and anti-social behavior and all the litter and mess it leaves behind.” . He added: “We simply will not tolerate anti-social behaviour, which is often perpetrated by large groups traveling from other areas and behaving with no respect for the community they are visiting. And yesterday we used public spaces legislation to tackle this.” Eighteen traffic violation citations were issued to those traveling to and from the area, including not wearing a seat belt and causing an obstruction while parked. Seven grills also went out due to the dry and dangerous conditions. Police said the owners of the stereos managed to get them back from a police station at the end of the day and were “advised about using them in public places”.
