Police have seized crates of beer, cider, alcopops and vodka from a group of 30 years having a party on Abersoch beach.

All of the youths were aged between 15 and 16 and had brought along supplies for a night-time party despite temperatures dipping close to freezing.

Gwynedd South Police shared pictures on Facebook of bottles of Sol and Corona beer, WKD bottles, a pack of Strongbow cider and at least one bottle of Smirnoff vodka.

North Wales Live reported that police have begun cracking down in the region following a series of under-age parties in the area.

All the youths involved will now receive a written warning about breaching coronavirus regulations that prohibit outside gatherings of more than four people.

Their parents will also be sent letters by the police.

In response to the Facebook post, a number of people condemned parents for not keeping a close enough eye on their children.

Others suggested a dispersal order in nearby Pwllheli may have prompted the Abersoch party.

The 48-hour order was put in place this weekend following “increasing incidents of anti-social behaviour and disorder/violence amongst youths in Pwllheli”.

District Inspector Lisa Jones said that anyone who is asked to leave the area by a police officer must do so.

Returning to the area may result in arrest, she added.

Parents in particular are being asked to ensure they know where their children are – and to make them aware of the dispersal order.

DI Jones said: “We are committed to ensure the actions of a disorderly minority do not affect our community.

“We will not tolerate behaviour which brings misery to our residents.

‘This is one of a number of measures at our disposal, and our officers will be visibly patrolling in the area throughout the dispersal period.

“I would like to thank the local community for your continued support.”

In recent weeks police have been tackling a spate of parties involving under-age drinking in southern Gwynedd.

Earlier this month officers confiscated alcohol after breaking up a night-time beach party involving more than 15 teenagers on Tywyn.

Police said it was clear many at the party were not observing social distancing, with many “hugging” each other.

And last weekend officers from Dolgellau and Tywyn were called to a party of more than 30 youths involved in under age drinking at Tywyn local cricket club.

In all three incidents officers were left to clean up the mess.
