A DRUG supplier is facing a lengthy prison sentence for a terrifying campaign of violence and intimidation which followed a bust-up with one of his street dealers.

Christian Collyn Foster held his former friend's sister and mother against their will for three days and tried to blackmail the younger of the two women.

The 32-year-old also raped the dealer's girlfriend when the dispute between the two reached a more sinister and violent height.

Foster, from Middlesbrough, was due to go on trial yesterday on a string of charges arising from the bust-up which lasted at least four months.

But at the last minute, he changed his pleas and admitted the allegations, and his case was adjourned for sentencing.

Foster's barrister, Simon Myers, admitted his client is facing a lengthy spell behind bars for his crimes.

Mr Myers did not ask Judge Anthony Briggs for a pre-sentence report from probation workers because of the certain prison sentence.

As he was remanded in custody, Foster was told: "When matters can be dealt with they will be, hopefully in the not too distant future."

Mr Myers said: "I would not urge the court to look at a pre-sentence report. He is inevitably going to receive a lengthy custodial sentence."

Foster, of Southwood, Coulby Newham, Middlesbrough admitted orally raping a 30-year-old woman at her home on December 20 last year.

A charge of vaginally raping the same woman on the same day will be ordered to lie on file when he is sentenced.

He also admitted falsely imprisoning a 49-year-old woman and her 16-year-old daughter at his home between September 13 and 16 last year after they had gone there to return some of his property.

An allegation of blackmailing the teenager between the same dates by demanding with menaces the return of a quantity of controlled substances was also admitted by Foster.

The Northern Echo has been told the case revolved around Foster's dispute with a "runner" who was dealing the drugs Foster was supplying on Teesside.

As a result of the fall-out, Foster is said to have planned a revenge mission which included blackmailing his former friend's sister into bringing him drugs he knew had been hidden away.
