He also said Tauqeer had not been shown as a wanted accused in the July 11 serial train blasts case and had no criminal record.

Sometimes, even an innocent person might run away fearing police action, Solkar said. Asked why the family did not file a missing persons complaint after Abdus went missing in 2006, Solkar said that after interrogation by various agencies they decided not to do so.

"We have no idea if he had any contact with SIMI functionaries like Safdar Nagori or Ahmedabad blasts accused Abdul Bashar," Solkar said.

Abdus, who was educated in a convent school in Mumbai and then acquired a diploma in engineering, was also a Microsoft Certified software engineer, he said.

After completing his education, he worked with a franchisee of Wipro computers and with software firm Datamatix in the city, Solkar said.

However, in 2001 he quit Datamatix and his family had no idea about his source of income after that till he left them in 2006, he said.
