Dhaka - Two agents of the US Federal Bureau of Investigation (FBI) were due to arrive in Dhaka Sunday to help Bangladesh probe last week's troop mutiny that left dozens of army officers dead, a minister said.

"Agents from the Federal Bureau of Investigation are scheduled to arrive in Dhaka today to investigate and support Bangladesh's local investigators," the country's foreign minister, Dipu Moni, told reporters Sunday.

Foreign ministry officials said the two officials will come as an advance team to look into ways to assist Bangladeshi officials in investigating the February 25 mutiny that left at least 71 people, including 57 army officers, dead.

An official at the US embassy in Dhaka said that the FBI team would arrive in Dhaka shortly, but declined to give any specific date for their arrival.

Immediately after launching the official investigation into the Bangladesh Rifles carnage, Prime Minister Sheikh Hasina Wazed said her government sought help from the FBI of the United States and Scotland Yard of Britain for a credible investigation into the troop rebellion.

She also sought assistance from the United Nations.

Bangladesh launched three separate investigations by the army, home ministry and the Criminal Investigation Department after the 33-hour bloody mutiny that was quelled on February 26.

More than 1,000 Bangladesh Rifles soldiers were charged for their involvement in mutiny, killings, arson and looting of armouries insides the headquarters of Bangladesh's paramilitary border force. The authorities planned speedy trials for the mutineers, preferably in court martial.

Bangladesh's law minister said that the mode of the trial would be determined only after the investigation was completed.

As of Sunday, a total of 36 rebels, including a prime suspect, had been detained, as army-led joint forces remained deployed to capture other absconding rebels. (dpa)
