CORAL REEF has become the star of a viral video this week when a gang of Youtubers managed to sneak in and stay overnight, making full use of the facilities.

The video, posted on the youtube page of 'Rikke Brewer' has already gained almost 2,000 views in just over a day. 

Coral Reef re-opened in September following a £13.3m redevelopment and has been met with mixed reviews, due to complaints over the cleanliness of the changing rooms and the customer service.

The group in the video are seen climbing over the fence into Coral Reef, before being told to leave by a member of staff. 

They then appear to enter through a hatch which has been left open, as the waterpark closes, before walking through the back-rooms of the pool. 

After putting on high-vis jackets and masks, they are found by two members of staff, but somehow slip right past them and walk into what looks like the toilets. 

After hiding for three hours, the group  re-emerge after the park has closed, before jumping through the cafe and enjoying the swimming pool. 

The rest of the video shows the pranksters swimming around, jumping off the sides, and going down the slides.

Vincent Palizcka, director of environment, culture and communities for Bracknell Forest Council, said:  "We are aware of an incident that took place overnight at Coral Reef on Thursday, 2 November.

"The matter has been reported to the police and is now subject to an ongoing investigation. It is therefore inappropriate for us to comment any further."
