Sabeel Ahmed, one of the accused in the botched London [Images] and Glasgow car bomb cases, has admitted to charges of withholding information that could have prevented an act of terrorism.

The 26-year-old doctor from Bangalore admitted at the Old Bailey court house on Friday that he had failed to inform the police regarding the terrorist attack that would have been of 'considerable assistance'.

Sabeel's brother Kafeel Ahmed, who according to police smashed a car containing gas cylinders and detonators into the Glasgow airport, had died in a hospital of the severe burn injuries sustained in the failed bombing in June last year.

Sabeel was among those arrested in connection with the botched terror attack.

The Indian doctor was arrested near Liverpool's Lime Street station on June 30 last year and later charged under the Terrorism Act.

Sabeel, who was living in Liverpool at the time of attack, was the third person charged over the failed bombing. Two other men, accused of conspiracy to cause explosions, face trial later this year.

On June 29 last year, two cars containing petrol, gas cylinders and mobile phone detonators were discovered in Central London. The next day the burning Jeep Cherokee was driven into the main terminal building at Glasgow Airport.

Jonathan Laidlaw, for the prosecution, told the court that the airport attack was intended to be a suicide mission after the earlier attacks had failed.

He said: "One assumes that the nature of the attack in terms of what was planned had changed because of the failed attempts in London. They appeared now to have been working on the basis they were likely to be arrested and the attack to be conducted at Glasgow was to be a suicide attack likely to result in the loss of both their lives."
