Drug dealers who ran a "sophisticated" £70,000 operation from a house in Worcester have been warned they are facing long jail sentences.

Two of the men would bring heroin and cocaine from Birmingham in taxis and hire cars to avoid detection and set up a base in the home of a third man in Cromwell Crescent, Worcester Crown Court was told.

They would then use dedicated pay-as-you-go phones for dealing and broadcast a message to all the contacts in the area, Siobhan Collins, prosecuting, told the court.

The message would read "on till seven. Pukka stuff" and they would then take the drugs to pre-arranged locations.

Judge Robert Juckes, QC, said it was an operation that had become "sadly familiar" to the courts with the drugs being supplied from Birmingham and sold in Worcester.

Itsham Razaq, aged 24, of Wood Lane, Handsworth Wood, Birmingham, Rashid Sadiq, aged 44, of Albert Road, Aston, Birmingham and 54-year-old Mark Burnham, now of Laburnum Walk, Upton upon Severn, all pleaded guilty to conspiracy to supply class A drugs.

Miss Collins said Sadiq had travelled from Birmingham on July 15 last year, the last day of a scheme that had run since April and involved them spending eight hours a day in Worcester dealing drugs.

"It was a sophisticated and well-crafted operation," she said. "They would travel separately and use hire cars or taxis to make regular journeys."

They would meet at Burnham's house in Cromwell Crescent, and Burnham would use his car to make the deliveries. Early in the afternoon, police saw what was happening and stopped them, Miss Collins said.

Sadiq, who had been lying across the back seat, tried to run but was caught after a struggle and Razaq was at the house when police arrived. A search uncovered £800 in cash and drugs in individual £10 deals worth a total of £150 along with the phones.

Analysis showed they had been running the operation regularly for three months and police estimated the total value of the dealing at around £70,000.

Ayoub Khan (CORRECT) defending Sadiq, said he was a single parent of three young children. He had not gained financially from his part and he just passed on the cash to others above him in the chain.

John Lucas, defending Razaq, said he was much younger than the other two and had just been acting as a "runner" delivering packages of drugs.

Belinda Ariss, defending Burnham, said he was now involved in drug and alcohol rehabilitation programmes and was acting as sole carer for his partner.

Judge Juckes said all three were facing substantial jail sentences and remanded them in custody to return to court for sentencing on August 7.
