A man was Tasered during an intense confrontation with police when he was caught drinking what police 'guessed' was alcohol in public.

Joshua Ford, 26, pleaded guilty to one count of possessing an open container of liquor in a public place, after he was caught with a can near Theatre Lane in Canberra on August 2.

However, magistrate Robert Cook dismissed the charge on Monday after the prosecution couldn't prove the can, which was inside a stubby holder, actually contained alcohol.

'It's a good guess ... but you've got to have more than that,' Mr Cook said. 

Bodycam footage from shows Mr Ford struggle when confronted by three officers who then Tasered him until he laid still on the ground.

As officers approached Mr Ford shortly after midnight, the one wearing the bodycam asked: 'Do you wanna put the drink down, mate?'

Mr Ford responded: 'How come?'

The officer quickly shot back: 'Because you are drinking in public, and you've just made a c**k of yourself calling out to us.'

Another police officer moved to take the can from Mr Ford and told him 'you can't drink in public'.

'Don't touch me, brah,' Mr Ford said.

Immediately, the officer wearing the bodycam grabbed Mr Ford's arm and told him he was under arrest. 

The three officers began to force Mr Ford to the ground as he struggled to free himself. 

The group Mr Ford was with yelled at police as he continued to squirm on the ground until the officer wearing the bodycam pulled out his Taser.

'Taser, Taser!,' he yelled before shooting the device at Mr Ford.

He then told Mr Ford: 'Stop resisting and get on your back.'

Mr Ford yelled 'f**king cops' before being Tasered a second time.

The footage ended with Mr Ford crying on the ground as officers handcuffed him. 

ACT Police claimed Mr Ford was with a 'hostile crowd' and acted 'aggressively'.

The officers' actions will be subject to an independent review.
