Two men have been arrested on suspicion of attempted murder after a man was slashed on the stomach at Thorpe Park.
Emergency services were called to the scene in Surrey shortly before 5pm on Saturday as eye-witnesses reported seeing “blood all over the floor”.
The popular visitor attraction was put into ‘lockdown’ following the alleged assault which happened near the exit of the park, the Mirror Online reports.

Two groups of people were allegedly involved in an altercation which left a man in his 20s with a wound to his stomach.
Police said he has now been taken to hospital and is in a serious condition but that no one was else injured during the incident.
Cops have arrested two men, also in their twenties, on suspicion of attempted murder.
Detective Inspector Andy Greaves said: "I'm keen to hear from anyone who saw what happened or who has video footage of this assault.

"The two groups of people were close to the exit inside the park on the bridge when the assault happened.
