Three men arrested in connection with the deadly suicide attack on the Marriott Hotel in the Pakistani capital were on Friday remanded to police custody for questioning by an anti-terrorism court.
A hitherto unheard of group called the Fidayen-e-Islam had claimed responsibility for the attack, which killed nearly 60 people, including the Czech ambassador, two US marines and a Danish intelligence official.
The accused were brought to court under tight security and a police officer sought their remand for 10 day, saying police hoped to arrest more persons with the help of information provided by the three suspects.
Judge Sakhi Muhammad Kahut remanded the trio to police custody for seven days and ordered police to produce them in court again on October 24.
The three men Dr Usman, Rana Ilyas and Hameed Afzal were arrested from the northwestern city of Peshawar and central Punjab province a day ago, police sources said.
They are suspected of facilitating the suicide bomber who carried out the attack and having close links with extremists, the sources said.
The government had formed a committee of police officials and experts from security agencies to probe the attack. The panel has presented a preliminary report to the Prime Minister. The attacker rammed a truck packed with 600 kg of explosives into the main gate of Marriott Hotel on September 20, hours after President Asif Ali Zardari made his maiden address to a joint session of parliament.
Interior Secretary Syed Kamal Shah has admitted in a meeting of the Senate's Standing Committee on the interior ministry that the blast was result of a defective security system. The Islamabad police chief also stated that intelligence agencies had informed police about an explosive-laden vehicle entering the city to carry out an attack.
