Indian doctor Mohammed Haneef, charged with 'recklessly' supporting a terrorist organisation, had a chat with his second cousin Sabeel Ahmed in an internet chat room about the birth of his child just days before the attack on Glasgow airport.

Haneef and Sabeel Ahmed, who is also a doctor and charged by British police with having information that could prevent an act of terrorism, last communicated online on June 26 -- three days before the undetonated car bombs were located in London [Images] outside a popular nightclub and in upmarket Park Lane, media reports said.

Details of Haneef's links to UK terror suspects were revealed in documents used by Immigration Minister Kevin Andrews to revoke the Indian doctor's visa, released by Haneef's lawyers.

Haneef's contact with Sabeel Ahmed, who was the third person to be charged in connection with last month's botched car bomb attacks in London and Glasgow, was about the birth of his first child, Fairfax newspapers reported.

Ahmed's mother visited Haneef's wife after the birth in Bangalore, India, and passed on the good news, the report said.

Haneef's most recent contact with Kafeel Ahmed, who allegedly drove a blazing explosives-laden jeep into the Glasgow airport, was in March.

Haneef, is being held in a Queensland prison charged with providing support to a terrorist organisation. His next court appearance is scheduled for August 8.
