The brother of the man who died after attacking Glasgow airport with a car bomb has pleaded guilty to withholding information about the attack on 29 June 2007.

Doctor Sabeel Ahmed, 26, admitted at the Old Bailey today that he had failed to provide police with information about the failed suicide attack. He was arrested in Liverpool and charged on June 30 last year.

Ahmed, originally from Bangalore in India, was the third person to be arrested in the investigation.

He is the brother of Kafeel Ahmed, who was the driver of the burning Cherokee Jeep that drove into the terminal building at Glasgow airport.

The car was laden with petrol and gas canisters but the improvised bomb failed to go off. Kafeel was arrested at the scene, after being hosed down by a police officer but subsequently died on August 3 after suffering burns to 90% of his body.

Prosecutor Jonathan Laidlaw said the bomber had sent his brother a text message before the Glasgow attack directing him to a draft email containing his will and instructions on how to mislead investigators.

Mr Laidlaw said: "Later on June 30, after the attack in Glasgow, he (Sabeel) came into possession of significant information about the attack and those responsible for it.

"Thereafter he failed to make the required, or any, disclosure and he had, as his plea of guilty now demonstrates, no reasonable excuse for that failing."
