ONE of Oxford’s biggest drug dealers was snared by an undercover police officer dressed as a delivery driver.

Clifton Bullock was caught after a package of cocaine from Costa Rica to his Headington home was intercepted at East Midlands Airport.

A police officer posed as a UPS employee to deliver a replica parcel to the Heath Close address.

Once Bullock had signed for the delivery and confirmed the residence was his, uniformed officers arrested him.

But while the drugs were analysed and further investigations made, the 58-year-old dealer continued to offend on bail, notching up five more offences.

Jamaican-born Bullock, who has numerous previous convictions for drug offences, was yesterday jailed for five years and eight months at Oxford Crown Court.

Prosecutor Jennifer Edwards said the package from Costa Rica, which arrived in August 2009, contained 26.7g of cocaine at a “very high” purity level, worth up to £9,500.

While on bail, Bullock was next arrested on December 12, 2009, as he cycled along The Slade in Headington. He was found with a Kinder Egg chocolate containing two wraps of crack cocaine and 10 wraps of heroin.

In January 2011, officers spotted Bullock’s VW Golf at Shotover Hill with an “interior fogged up with smoke” and found crack cocaine and heroin.

Now on bail for three incidents, Bullock was seen dealing drugs outside the Oxford Night Shelter in Luther Street on October 14.

Bullock admitted three counts of possessing Class A drugs with intent to supply, two counts of possessing Class A drugs and one count of supplying Class A drugs.

Judge Mary Jane Mowat was told Bullock has more than 37 previous convictions going back 30 years.

In 1999 he was jailed for 45 months at Oxford Crown Court for possessing crack cocaine and heroin with intent to supply after he was stopped in Ashmole Place, Blackbird Leys.

On that occasion a judge accepted Bullock’s basis of plea that he was merely returning a package of drugs he had found in a car he had recently bought from one of the occupants of the flat.

Lauren Soertsz, defending Bullock yesterday, said her client had been mixed up with selling and taking drugs since the age of 14 and wanted to move away from Oxford after his release from prison.

She added the cycle of bail her client was placed in had not helped his situation.

Outside court, Pc Paul Phillips said: “Hopefully with him receiving this sentence he’ll realise it’s time for him to change his ways.”
