New Delhi - Ajmal Amir Qasab, the lone terrorist arrested in the November 26 attacks in Mumbai was Monday remanded in police custody until February 2, a news report said.

Qasab has been in police custody since his arrest on the night of November 26 and has been booked in 12 cases including murder, attempted murder, waging war against a country and criminal conspiracy.

The multiple gun-and-bomb attacks on India's financial hub between November 26-29 killed at least 173 people, including 26 foreign nationals.

Qasab was to be produced in court but due to security concerns, magistrates and court officials visited him at an undisclosed location in the city, the PTI news agency reported.

"It was argued that the police had to carry out further investigations in the case for which the custody was needed," public prosecutor EB Dhamal told PTI.

Qasab was last remanded to custody on January 4. He, along with accomplice Ismail Khan, attacked the Chattrapati Shivaji Railway station, one of the sites of the attacks, on November 26, killing 58 people and injuring over 100, police said.

Relations between India and Pakistan have deteriorated since the Mumbai carnage. Indian security agencies claimed that Pakistan-based Lashkar-e-Taiba (LeT) militant group masterminded the attacks and Qasab is a Pakistani national from Punjab province.

India has handed Pakistan evidence collected during investigations into the Mumbai attacks which it claims show links to elements based in the neighbouring country. It has asked the Pakistani government to take action against these elements and extradite the suspects to India.

Pakistan has rejected the demand and insisted that the culprits would be prosecuted and punished according its own laws.

Pakistan's top security official Rehman Malik last week announced that the country had detained 71 people, including at least four LeT commanders, in a crackdown in connection with the Mumbai carnage. (dpa)
