Two of the accused in the July 11 Mumbai serial bomb blasts case were subjected to narco-analysis tests at the Lady Bowring and Curzon hospital in Bangalore for the second successive day on Thursday.

Official sources said Kamal Ahmed Sheikh and Tanveer Ansari, who were among the nine arrested in connection with the blasts in local trains, were brought to Bangalore by the Mumbai police on Sunday under tight security and put to brain-mapping at the Forensic Science Laboratory the next day.

The duo have been brought in Bangalore to testify some valuable information the Mumbai police had gathered in the case.

Over 200 people had lost their lives and 800 sustained injuries in the serial blasts.
