SOUTHAMPTON thrill-seeker Ally Law has released another video of him and friends sneaking into a water park - sparking a security review at the facility.

The renowned Youtuber this time targeted Splashdown in Poole, sneaking in just after 2am on Tuesday.

In the video, released on Law's Youtube channel, he and four friends can be seen climbing over a barbed wire security fence, before gaining access to the inside of the water park.

It later shows the group launching themselves down the flumes, often with just a torch to light their way through the pitch black, during the three hour long session.

The video, uploaded yesterday, has already been watched more than 370,000 times.

But bosses at the water park have heavily criticised Law's antics, saying they ‘could have resulted in tragedy’.

Jackie Richmond, co-owner and group marketing director, said a “thorough review of security” had been carried out following the incident, as well as a check of “all on-site facilities”.

“Whilst the people who broke in and used the premises without permission thought it would be a laugh, they are very lucky to be in one piece,” she said.

“Water levels and plunge pools can be drained overnight and in the pitch black this would be impossible to see.

"Dropping multiple feet into a concrete ‘pool’ could have severe implications for the person falling, resulting in significant injury or worse.”

She added: “We have a lot of health and safety rules regarding the correct use of the flumes for very good reasons and their flouting of them, especially in the dark, could have easily resulted in a tragedy.”

Splashdown’s owners discovered the break-in later that day and contacted the police.

A spokesperson for Dorset Police said the incident was reported to them just after 9am on Wednesday.

The spokesperson said: “We were called at 9.04am to be informed that a number of people had entered Splashdown at Tower Park at night, without permission, to film a video.

“The matter has been passed onto the neighbourhood policing team to look into.”

Self-styled 'urban explorer', Law, who originates from Southampton, has previously targeted facilities in his home city.

Last October, he filmed a video inside The Quays Swimming and Diving Complex.

Law also filmed a video of him and friends inside a closed St Mary's stadium and another in IKEA on West Quay Road.

He gained national media attention earlier this year when he 'entered' the Big Brother house, in Hertfordshire, scaring celebrity housemates in the process.
