According to sources, investigations into SIMI activities prior to the Jaipur blasts of May 13 had also thrown up Samee’s name and the Karnataka police had even zeroed in on a student of the Malik Sandal Institute of Art and Architecture. But no arrests were made after the police were told that the student’s name was Mohammed Samee and not Abdul Samee.

Sources said investigations had returned to the architecture student after his name figured in the interrogation of Shahbaz Hussain in Jaipur.

Samee’s family in Bijapur, however, say the arrest is a result of mistaken identity. His father Raj Ahmed Bagewadi has produced college records to show that his son goes by the name of Mohammed Samee Bagewadi and not Abdul Samee.

The investigations surrounding the architecture student show that the Bangalore police is also taking the same line as the Jaipur, Ahmedabad and Delhi blast cases.

Investigations into the Bangalore blasts have until now produced little results. A parallel case of dumping of a large quantity of ammonium nitrate on the outskirts of Bangalore, a day before the blasts, is also being probed.
