Shocking video shows DOZENS of Brazilian prisoners queuing up to snort COCAINE off a table at a party organised by one of the gangs controlling the jail

This is the astonishing moment inmates queue up in prison to take their turn snorting cocaine from a table with more than 100 lines of the class-A drug neatly arranged on it.

More than a dozen excited jailbirds were filmed openly taking drugs in a packed corridor of the prison as others queued up in single file behind them.

A small handful of men appeared to be in loose control of the situation, making sure the noisy prisoners crowding round the table didn’t knock it over and scatter the cocaine all over the floor or treat themselves to more than their fair share.

One of the inmates even laughed as he posed for one of the inmates holding mobile phones in their hands after his illegal use of the drug.

The shocking images were filmed in the main prison in the southern Brazilian city of Porto Alegre.

Police confirmed today they were investigating the drug orgy, said to have taken place during a party organised by one of the gangs that control the jail.

Thirteen men are filmed snorting cocaine from the table - where the drugs are immaculately arranged in six rows of 20 lines of cocaine each - in the 90-second video which cuts off when just a handful of the 40-odd men waiting their turn have had their go.

Military police have launched an investigation which is understood to be running parallel to others by prison bosses and a regional drug squad.

Regional drugs squad police chief Mario Souza confirmed: “We are investigating from the perspective of drugs trafficking.

“We are going to look into questions like when the video was taken as well as confirming the place it was taken in and investigating the context.”

Cezar Schirmer , Public Security Minister for the state of Rio Grande do Sul which Porto Alegre is part of, branded the footage “unacceptable, provocative and nasty.”

He said he had ordered a police inquiry to get to the bottom of drugs trafficking and the use of mobile phones in prison.

“The identities of those involved in the recording and the aspects of consumption and drugs trafficking, as well as the entry of drugs and mobiles into prison and the circumstances surrounding this incident and the place and date, are not yet clear. They need to be investigated fully and immediately.”
