A topless suspected drug dealer struggled with plain-clothed police officers trying to arrest him, sending white powder flying in the process.

The man, 34, was stopped by officers from the Metropolitan Police outside a Screwfix store in Brixton, south London.

Video footage captured by a passerby shows the man rolling around on the floor as he attempted to get away from police just metres from the front entrance to the store.

Dressed in just grey jogging bottoms and one shoe, the suspect could be seen struggling to free himself from two officers' grip as they attempted to pin him to the ground.

One appeared to knee the suspect in the side as he continued to resist arrest. 

A third officer rushed in, helping tip the man onto the floor, where he was finally pinned down by the trio.

But the suspect did not give up, continuing to fight back as one officer attempted to handcuff him.

As his arm was slammed to the ground, a bag appeared to burst, spreading a large pile of white powder on the floor in front of him. 

The wind could be seen taking bits of the powder, and what appeared to be a wrapping, into the air and away.

The suspect was arrested on suspicion of possession with intent to supply Class A drugs and on suspicion of assaulting two emergency workers. 

A force spokesperson said: 'A 34-year-old man remains in custody after he was arrested on suspicion of possession with intent to supply a Class A drug and assaulting two emergency workers.

'The man was stopped by plain clothed officers outside a shop in Brixton, south London on Tuesday, 14 April.'
