Drug dealers and knives at Thorpe Park

There have been 32 cases of confiscated cocaine 55 cases of class C cannabis and 43 cases of class B cannabis.

There has also been four incidents where police have recovered drugs that were brought to the family theme park in Chertsey with "intent to supply."

On two of those occasions drug dealers brought cocaine to sell in the park grounds. On the other two it was cannabis.

Twenty cases of confiscated weapons were also seized by Surrey Police including six blades and three cases of CS gas.

Other drugs taken from park-goers included six cases of confiscated amphetamines, three cases of Ketamine, and two of MDMA (the primary ingredient used in ecstasy tablets).

Sally Heasman, 48, from Worthing said: "It's a bit scary actually, it just wouldn't have occurred to me that it happened here.

"I mean you let the kids go off on their own but there could be drug dealers hanging around."

Daughter Alice Heasman 16 said: "I wouldn't have thought it at all, I don't understand why people would come to a theme park and bring drugs and weapons."

One father from Addlestone who did not want to be named said "It's no good, they need to find the people who are selling the drugs in there and put them in prison and throw away the key."

A spokesperson for Thorpe park said: "As the health and safety of our guests and staff is our primary concern we have a zero tolerance on anti-social behaviour, we work closely with our local Drugs Liaison Officer and are extremely vigilant in preventing contrabands entering Thorpe Park.

"We therefore undertake a very proactive approach to security, by which in 2009 we have so far carried out 83,461 random searches, an increase of 309% on 2007.

"July is one of the busiest periods at the Park and by way of percentages, more searches are carried out."

A spokesman for Surrey Police said: "Police in Runnymede work closely with colleagues at Thorpe Park to ensure the park remains a safe environment for members of the public to enjoy.

"The Runnymede Tactical Neighbourhood Teams carry out passive drugs dog operations several times a year supporting staff at the entrance to Thorpe Park.

"Surrey Police takes crimes involving drugs and weapons extremely seriously and the number of searches taking place at Thorpe Park show there is a robust policy in place to prevent disorder.

"The park is used by nearly two million people each year and the number of offences and people being stopped with weapons or drugs remains a very small percentage."
