A Bradford man conspired to supply hard drugs for distribution on the streets of Britain, a Court heard yesterday.

Anwar Khan, 38, was the right-hand man of the person running the northern end of the conspiracy, Leeds Crown Court was told.

Khan, of Sandford Road, Bradford Moor, is one of six accused of conspiring to supply heroin between August and October 2004.

Prosecutor Sean Morris said the London end was run by Yuksel Koc, 36, a Turk who organised the distribution and sales, and another man who imported and stored the drug.

Another Turk, Semih Oskeskin, 41, was Koc's assistant, while Anwar Khan was the right-hand man of Asif Khan, 27, of Burnley, in the north, the jury heard. Kasper Winblad, 24, a Dane, had the role of drug deliveries and cash collection, while Kelly Lowery, 32, of Burnston, Manchester, provided a safe place to store the heroin for distribution it was claimed.

Mr Morris said the accused were observed by police officers who sat near them at regular meetings they held. The conspirators also used phone boxes and mobile phones and undercover officers would note the numbers of kiosks.

Mr Morris said there were two seizures of drugs by police, one involving a Bradford taxi driver, Ibrar Ahmed.

Police stopped Ahmed, 31, on the M62 as he returned to Yorkshire from a meeting in Manchester. Ten kilos of heroin in a Twix confectionery box were found in his car boot. His house was searched and £30,000 seized, said Mr Morris.

He added: "It must have been patently obvious to the conspirators that they had lost a large consignment of heroin worth an awful lot of money. It's obvious that after such an expensive calamity all the major conspirators would have to meet and the police were there to video it."

The jury watched a video showing some of the alleged conspirators in animated discussion.

The defendants were arrested on October 5, 2004 and 20kg of heroin in two boxes was recovered from Kelly Lowrey's home. Anwar Khan was arrested in the departure lounge of Manchester Airport as he waited for a plane to Pakistan.

Anwar Khan, Asif Khan, Koc, Winblad, Oskeskin and Lowrey all plead not guilty to the conspiracy charge.

The trial, which is expected to last for eight weeks, continues.
