Charlestown, a picturesque Cornish village known for its role in the popular BBC drama "Poldark," is grappling with a surge in anti-social behavior attributed to underage drinkers, leading to its moniker "Britain's Ibiza." Residents report acts of vandalism, littering, and disruptions that have instilled fear among the elderly and led businesses to close early.

Inspector Simon Andrews of Devon and Cornwall Police stated that the force has enacted dispersal powers to address the rise in issues, particularly during the summer holidays. These powers allow officers to move on individuals causing harassment, alarm, or distress, with non-compliance risking arrest or being sent home. The increase in disorder has been observed around public events like regattas and food festivals.

Harbour master Mathew Chapmen described a pervasive issue of youth disrespect toward adults and property. He has personally confronted youths throwing rocks and traffic cones into the harbor and noted a previous year-long ban on harbor jumping due to escalating anti-social behavior. Chapmen expressed a need for stricter rules for teenagers, suggesting that current penalties are insufficient.

Businesses in the village have also been affected. Patrick Hunt, owner of The Deck, called the recent behavior "probably the worst we've seen all year," detailing instances of cones being thrown into the harbor and youths shouting at people. Tracey Brown, owner of Charlestown Fish Co, reported disturbances that led to police attendance and guest refunds, alongside rubbish left by youths and items being moved. Bruce Keeping, owner of Charlestown Water Sports, has experienced items being thrown into the harbor and some of his equipment being taken.

Witnesses have described scenes of "carnage," with instances of swearing, young girls being disruptive, and even an ambulance being called to a local establishment due to patrons being sick. Some residents have pointed to parents providing alcohol to minors and then leaving them unsupervised in public spaces.

Charlestown, which hosts ancient tall ships and serves as a filming location, is home to nearly 500 households but also has a high concentration of bars and restaurants. While many visitors and locals enjoy the tranquil atmosphere, concerns have been raised for years that its popularity, amplified by the "Poldark effect" and a decline in similar venues in nearby towns, has come at a cost. Cornwall councillor James Mustoe welcomed the police intervention, calling the behavior "unacceptable."
