A London drug dealer who was caught in Ewell and went on hunger strike for more than 20 days in custody, then passed more than 150 wraps of class A drugs, has been jailed.

Mohamed Wallace, 24, was stopped in Kingston Road on April 6 as part of Surrey Police’s Operation Viking, which aims to tackle cross-border drug dealers.

Officers searched Wallace and the car, finding three mobile phones, some cash, a tub of cocoa butter, bio oil and feroglobin liquid, which has laxative effects if too much is consumed.

He was taken first to East Surrey Hospital, because police believed he might have been hiding drugs internally, but he refused an x-ray and became aggressive towards officers.

Then he was taken to police custody, where he was under constant observation, and he went on hunger strike, meaning officers had to apply for an extension to keep him detained.

Detective chief inspector Mark Preston said: “Mohamed Wallace put his health at considerable risk while in custody by going on hunger strike, and could have saved himself a lot of suffering.

“This is again another example of our officers proactively patrolling the streets to look for potential offenders and is proving a success in disrupting drugs networks that have come into our county.

“Operation Viking is not stopping any time soon and will continue to make life as uncomfortable as possible for drug dealers coming here to cause trouble.”

Wallace was first charged with driving while disqualified, driving without insurance, breaching an anti-social behaviour order and possession of cannabis; he pleaded guilty to all these charged on April 26 at Staines Magistrates’ Court, and was sentenced to eight weeks in prison.

The next day, prison staff found him trying to internally secrete drugs, and after a struggle two large plum-sized bags were found – one containing 59 packages of heroin and 45 packets of crack cocaine, and the other containing 56 packages of crack cocaine.

These were the bags he initially hid inside himself when he was first arrested.

Wallace, of no fixed abode, pleaded guilty to possession with intent to supply class A drugs at Guildford Crown Court on Wednesday, November 15.

He was sentenced two days later to four years in prison.

Wallace was also sentenced for possessing identity documents with intent, because he gave police a driving licence with someone else’s name when arrested.
