A prison librarian from Penge who tried to buy a gun and ammunition on the dark web has been jailed.

Dwaine Osbourne, of Avenue Road, was arrested in October 2015 after he attempted to buy a Glock 19 handgun and 100 rounds of ammunition online.

In a search of his home officers found that Osbourne, who worked in the library at HMP Brixton, had a media drive, two stolen passports and a police uniform.

He was bailed pending further enquiries but was re-arrested on February 17 last year when it was discovered that the media drive contained senstive information from the prison.

The information included a listof all inmates and their cell locations, along with a list of all staff and their personal data.

At the time of his second arrest officers also recovered drug wraps, scales, cutting agent, cash and cocaine.

Osborne was charged with nine offences including attempting to purchase a firearm and ammunition and possessing class A and B drugs with intent to supply. Osborne pleaded guilty to six charges and was sentenced yesterday at the Old Bailey.

Andy Tickner from the Organised Crime Partnership said: “People looking to obtain illicit goods and services under the supposed anonymity of the dark web continue to discover that they can be traced and identified.

“Ensuring that firearms cannot be sourced in this way is a priority for the NCA. We will work tirelessly to prevent and disrupt those involved in the buying and selling of firearms on the dark web.”

The Organised Crime Partnership brings together officers from the National Crime Agency and the Metropolitan Police Service to protect London from the harms inflicted by organised crime.
