The parents of Kafeel Ahmed, detained in connection with the failed UK terror plot, on Saturday told investigators that the man who tried to crash a jeep laden with crude bombs into Glasgow airport was their son.      

"They (the parents Maqbool Ahmed and Zakia Ahmed) said it was Kafeel," an officer with the investigation team told PTI without elaborating.

It was not immediately clear how Kafeel's parents came to the conclusion amid reports that the man who drove the vehicle used to hit the Glasgow airport was a Lebanese.

But City Police Commissioner N Achutha Rao maintained that they have not made that admission during questioning.

Police, central crime branch and Intelligence Bureau sleuths accelerated the probe to unravel the Bangalore angle of the British terror plot.

"All angles are being probed. We are still inquiring. It's at a nascent stage," Rao said.

A computer and hard discs seized from the residence of Kafeel and his elder brother Sabeel Ahmed from their Banashankari residence is now under the possession of the cyber crime cell, which will analyse the stored data.

"The cyber crime team will scrutinise e-mails, Internet chats and other data stored in the hard disc to find out whether the brothers had any link with any terror outfit," police said.

Sources said that questioning of parents of Kafeel-Sabeel and Mohammed Haneef has not thrown any light on possible terror links.

"Nothing has emerged so far. No incriminating documents have been seized. So far nothing has come to light," Rao said.      

Police are also believed to have questioned some people in the close circle of the two families to get clues and more information on the antecedents of the brothers, as well as their cousin Haneef, who was detained in Australia.      

"We require two to three weeks to complete the investigations," Joint Commissioner of Police (Crime) Gopal B Hosur said.

Bangalore police have, meanwhile, submitted a report to the Intelligence Bureau following the interrogation of members of the two families and are in touch with the IB.      

In the wake of Bangalore link to the UK terror plot, police have sought creation of a full-fledged Anti-Terrorist Squad. The present small dispensation is collated from Bangalore police.

Intense media glare and highly publicised questioning have been telling on the two families.

A relative of Kafeel-Sabeel who met their parents on Saturday, told media persons outside their residence that Maqbool Ahmed is physically sick, while his wife Zakia was currently 'under tremendous mental pressure.'
