Mohammed Ajmal Amir Kasav, the lone terrorist caught alive during the November 26 terror attacks, on Thursday was in Mumbai for his alleged involvement in the killing of ATS chief Hemant Karkare and two other senior police officers.

Due to security concerns, Kasav was not produced in a regular court and a magistrate and a public prosecutor were taken to the police lock-up, where the terrorist was lodged.

"When asked by the magistrate if he had any complaints against the police, Kasav said he had none," Additional Public Prosecutor Eknath Dhumal said referring to the remand proceeedings.

Following brief arguments regarding his custody, the terrorist, who has not yet obtained any legal representation, was sent to police custody for 14 days.

Kasav and terrorist Ismail Khan, who was killed in a shootout with the police, had allegedly ambushed and killed six policemen, including Karkare, Additional Commissioner Ashok Kamte and Inspector Vijay Salaskar, on November 26 night. The police have registered 12 terror cases in connection with the November 26 strikes in the city that left 183 dead and over 200 injured.

Kasav, who hails from Pakistan, has been booked under various charges, including waging war against India, murder, attempt to murder and sections of the Arms Act and Explosives Act.

The only one in the group of ten terrorists who attacked Mumbai to be arrested alive, Kasav has been kept in an undisclosed location since his arrest on November 26 in south Mumbai.

The city Crime Branch, which has Kasav's custody, had requested the magistrate to hear the remand application in the police lock-up due to security concerns with regard to his production in an open court.
