A mother plays happily in the sand with her young son – both oblivious to the sex and yobbish antics around them.
Astonishingly a 15-year-old girl performed a sex act on a boy aged just 14 as they frolicked in shallow water at Troon’s South Beach.
Other hate-filled youths abused police as they tried to assist a teenage girl sprawled incapable on the sand.
And as both Troon and Ayr were plunged into Costa del Scumbag mode once again, decent visitors and residents have had enough.
The ghastly goings on have left folk furious – and prompted police into their biggest zero tolerance operation ever.
Senior officers have masterminded plans to crack down on the drunken louts – and used stop and search powers 300 times on Troon beach last week.
Some youths tried to bury their cheap vodka and tonic wine under the hot sands as police took away drink.
Inspector Sean Mangan praised his officers for cracking down on the marauding mobs who spill off packed trains from Glasgow and Paisley.
It should have been a quiet Wednesday, but with a forecast for hot weather it triggered an avalanche of sun and drink-seeking teenagers.
Insp Mangan said: “It does not just happen at the weekend – as soon as the schools and colleges stop it can happen any day.
“We seized and destroyed all drink from both under-agers and those in their company we suspected of supplying it.
“And we have spoken to most of the off-licences in Ayr, Prestwick and Troon and most are very responsible.”
Again on Friday police made large numbers of searches on Ayr beach.
And one eyewitness said: “It was like being at a football match.
“While it was reassuring to see the police presence, it’s a sad day when we need that on our beaches.
“There was a van, several cars and squads of police on foot patrol – I have never seen that in Spain.”
On Troon’s South Beach three boys, aged 16, 15 and 13 were arrested for breach of the peace.
The 15-year-old girl and a 14-year-old boy were then arrested for the illegal sex act. All those arrested had visited the area for the day.
The trains – which have to be policed by British Transport Police which does not have enough staff – have again been proven to be the weak link.
Witness Lorraine Brett said: “I was at Glasgow Central when train loads of teenagers were leaving on their way to Troon. There were that many of them that lots of passengers had to wait for later trains as there was no seats left.
“I really don’t know why the police in Glasgow allowed them to board.
“I think trouble sadly may be part of the attraction for them.”
And Sian Mackie added: “The kids were drinking and causing havoc on the train.
“When I approached the conductor he stated “he wasn’t the police”.
“At the beach they were an absolute disgrace to their parents. There was swearing and the fighting started from noon. I personally heard several people asking them to stop swearing as there were children present, they were also sworn at.”
Other passengers spoke of drunken parents and kids so sun-burned they desperately needed water.
And others highlighted an off-sales in Troon doing a roaring trade in Buckfast tonic wine and MD 2020 – many bottles of which were later dumped empty on the beach.
