Indian doctor Sabeel Ahmed, sentenced to 18 months in jail for withholding information about his brother’s plot to blow up Glasgow airport, will be deported from Britain on Wednesday as he has already served the time while on trial.

Sabeel, 28, who worked at the National Health Service and had admitted that he failed to inform the police about his brother Kafeel’s plans to carry out the suicide bombing last year, will be escorted by two Metropolitan Police officers to Bangalore, official sources said on Monday.

The June 30 attack saw Kafeel driving a jeep filled with propane canisters into the airport terminal and set it alight. However, the burning vehicle failed to break through the glass doors and no one was injured, although Kafeel, an engineer, subsequently succumbed to his burns.

A London court was told last month that Sabeel received an email from his brother and details of his will before the attack. The court heard that he will be released from custody and deported to India because of the time he has already served while on trial.

Originally from Bangalore, Sabeel was arrested in Liverpool on June 30 last year and later charged under the Terrorism Act, 2000. He entered his guilty plea during a hearing at the Old Bailey in London.

Sabeel was the third person to be charged in the investigation and two other men who face trial later this year have been accused of conspiring to cause explosions.
