This is the dramatic moment a British tourist rugby tackled a notorious BOXER who stole his bag on a Thai beach.

Fraser William, 23, was paddling in the sea with his girlfriend when he saw the thug run off with his belongings in Krabi, southern Thailand, on April 24.

He sprinted over to the road as Suwit Puengsom, 31, was trying to make a getaway on a motorcycle. However, brave Fraser leapt at the thief and bundled him to the ground.

They went toe-to-toe while grappling with each other before the martial arts expert wriggled free and escaped on foot.

Police arrested Suwit, a former professional Muay Thai boxer, on Tuesday April 26 and he admitted stealing the Brit's bag at the Ao Nang beach in the early hours of the morning.

Brave Fraser told police he chased the thief without thinking. He said: 'I wasn't afraid. I just wanted to stop him from taking my stuff.'

Fraser's bag had around 5,000 THB in local currency, credit cards and hotel room keys. He chased after the robber and pushed his motorcycle but Suwit snatched the bag and fled from the scene.

Ao Nang police inspected the scene and went through the CCTV footage before finally identifying the suspect.

Officers issued an arrest warrant and arrested Suwit. They searched his room and found an outfit that matched the description and also found the same motorcycle seen in CCTV.

Police Colonel Somsak Thongkliang said: ‘Suwit still had an injury on his right knee while trying to escape from the tourist.

‘The suspect was a famous Thai Boxer with the nickname Den-Saenchai. We have already detained him and brought him to Ao Nang police station for further legal proceedings.’

The suspect has been remanded in custody.
