Former CBI court judge M L Tahiliyani will try Pakistani national Mohammed Ajmal Amir, the lone surviving terrorist of the November 26 terror attacks in the metropolis that left over 180 people dead.

Tahiliyani, currently Registrar (Inspection) in the Bombay High Court, will be the Special Judge to conduct the trial, city Police Commissioner Hasan Gafoor said on Monday night.

There are 12 cases registered against Amir and other accused in the carnage.

Ujjwal Nikam, who was the state counsel in the 1993 Mumbai serial blasts, has already been appointed Public Prosecutor for the trial.

Police are expected to file a chargesheet before January 24. Amir, whose Pakistani identity has been acknowledged by Islamabad, will face charges ranging from murder, attempt to murder and waging a war against the country, officials said.

The chargesheet will cover mainly Amir's conversation with his handlers in Pakistan, his interrogation report besides eyewitnesses who saw him spraying bullets on the night of November 26.

Police have decided to club all the 12 cases filed on the intervening night of November 26-27.

Sources in Maharashtra government have said the trial is likely to be conducted inside the high-security Arthur Road jail, where the trial and sentencing of nearly 100 accused took place in the 1993 blasts.
