A British man has been detained in Bulgaria after stealing a forklift truck and crashing into two cars before attacking local police - and himself - with a wrench.

The man has been named as John Kerry, 26, a Mixed Martial Arts fighter, and he is currently in hospital after going on a rampage in the popular holiday resort Sunny Beach earlier this month.

Bulgarian police say Kerry stole the forklift from a local warehouse in Sunny Beach, and proceeded to drive off down the road, crashing in to two cars in the process.

Detained: The man, named by Bulgarian police as John Kerry, 26, went on a rampage in Sunny Beach after taking anabolic steroids and other unnamed drugs and mixing them with alcohol

Violent: Kerry stole a forklift truck from a local warehouse and turned on police after he was apprehended, using a wrench from the truck, before he started beating himself in the head with it

Kerry had reportedly more than overindulged, as he was found with a cocktail of drugs, including anabolic steroids, as well as alcohol in his system.

A police spokesperson said: 'We tried to arrest him but he grabbed a foot-long metal wrench from the vehicle and used this to hold officers at bay.

'He then started hitting himself on the head with the wrench before then turning and running away.'

The policeman said the officers pursued Kerry and one of them was hit with the wrench and injured before the 26-year-old escaped again and this time ran into a petrol station.

Damage: As police caught up with Kerry, he appears to have attempted to lift a car with the forklift

The police spokesman said: 'We evacuated staff and customers at the petrol station, and the British man made his way then into a kitchen emerging with two knives.

'He was eventually put out of action by officers from a special tactical unit.

'After being neutralised, he was taken to hospital to be treated for self-inflicted injuries and when he is released he will be arrested for his inappropriate behaviour.'

Rage: When police tried to arrest him, Kerry grabbed a foot-long metal wrench which he used to fight off police officers before hitting himself in the head and then trying to run away

Taken in: He also threatened police with knives before he was finally apprehended and taken to hospital

They said that the man had arrived in the country as a tourist on September 21, and a blood test was taken which indicated he had been on anabolic steroids and other drugs mixed with alcohol when he went on the rampage.

The spokesman confirmed that he was a professional athlete training for MMA fights when he lost control of himself, apparently after mixing the various chemicals.

A hospital spokesperson said: 'The combination of drugs that he had effectively blown a fuse in his brain. It left him completely out of touch with reality.'
