A volunteer litter-picker who regularly clears rubbish on Barry Island said he has "never collected that much" from the rocks at edge of Whitmore Bay, after filling eight bags.

Included in the litter were 45 Nitrous Oxide cannisters and balloons.

The resident, who asked not to be named, cleared the litter this morning after yesterday's highs of 25°C saw people flock to Barry Island.

"It can be intimidating to clean it up at night, because there's so many around that laugh at you while you do it," he told Nub News.

"That's why I came down this morning, and I didn't expect that much to be honest. As well as the canisters and balloons, there were so many glass bottles.

"The carrier bags have the glass bottles, and then the black bags have cardboard and plastic in.

"I've never collected that much off that edge before. If I didn't pick that up, it would have got washed out to sea, and it happens on a daily basis.

"It's really annoying because it's a nice area on those rocks. You sit up there later in the day and you're in the shade looking out at the beach, but some people spoil it."

A spokesperson from South Wales Police said: "Nitrous Oxide has several legitimate uses but when inhaled, it can cause unconsciousness or death due to a lack of oxygen.

"Mixing alcohol with nitrous oxide can be fatal. It is illegal, in England and Wales, for anyone to sell nitrous oxide to people under-18, if they think they are likely to be inhaling it.

"The local community is asked that if they see any suspicious activity where nitrous oxide may be getting consumed, please report it to police on 101 and our officers will visit the area."
