A TRIAL of a pharmacy student and a 17-year-old youth was abruptly halted yesterday after both suddenly changed their pleas to admit their roles in a plot to rob G4S cash-in-transit vans.

The Bradford youth, who cannot be named because of his age, admitted a charge of conspiracy to rob.

Student Nisha Nadeem, 21, of Woodhall Park Crescent East, Stanningley, admitted an alternative offence of aiding and abetting a robbery bid at a Tesco store where she worked.

Both were remanded into custody by Judge Jonathan Rose at Bradford Crown Court until their passports were surrendered to the police.

They must then report daily to their local police station and were ordered not apply for any travel documents.

A probation report was ordered for Nadeem and the Youth Offending Team will prepare a report on the 17-year-old.

They will be sentenced on December 15, along with Nadeem's former boyfriend, Tariq Aziz, 20, of Leeds Road, Bradford, and two other males, who all pleaded guilty to the robbery conspiracy ahead of the trial.

During the trial, the jury heard that security guard Carol Lane was robbed of £11,500 by two armed raiders at Tesco's store in Bolton Road, Bradford, at 3pm on May 25 this year.

Prosecutor Tim Capstick said Miss Lane was approached by two males, one armed with a machete, after she had picked up bundles of money from Tesco.

She was knocked down and bruised in the struggle and her assailants made off with a locked canister of cash.

Their getaway vehicle, a Ford Focus, was later found burned out in Silverhill Road, Bradford Moor.

The four male occupants of the car had switched to a Ford Mondeo which crashed into a Subaru at the junction with Silverhill Drive and Upper Rushton Road.

The police found a lump hammer and a working taser in the Mondeo which came to rest against a wall and was abandoned by the raiders who fled the scene on foot.

The jury heard that a second robbery was planned at Tesco in Stanningley on June 26 but it was foiled by a tip-off to the police that three males in a Saab car were behaving suspiciously as they were wearing gloves and hoods in the summer time.

Nadeem, who worked as an assistant at Tesco in Stanningley, was to provide inside information to the robbers, the jury was told.

The youth was arrested by the police near Tesco in Stanningley with two of the males who had earlier admitted conspiracy to rob.

Tights, a balaclava mask, gloves, a knife and a lump hammer were found in the Saab.

The youth was later found to have been linked to the Ford Mondeo though fingerprint and DNA evidence.

Nadeem , who was arrested in July, had initially denied any involvement in the robbery plot, telling the police during interview: "I feel like I've been used."
