Police in Bangladesh say they have arrested the suspected ringleader of last week's border guard uprising that left 70 people dead.
A spokesman for Bangladesh's elite forces, A. K. Azad, says Tauhidul Alam and four other suspects are in custody following a raid in the capital, Dhaka.
The spokesman said Tauhidul Alam had met with Prime Minister Sheikh Hasina during negotiations and promised to surrender. But the mutiny went on for another day until army troops moved into the guards' headquarters last Thursday.
Authorities continue to search for 1,000 border guards and their accomplices.
Prime Minister Sheikh Hasina told supporters late Tuesday that the attack was part of a conspiracy to destabilize Bangladesh.
A U.S. State Department spokesman said Tuesday that the U.S. Federal Bureau of Investigation, FBI, has agreed to help Bangladesh in its investigation.
Border guards staged a two-day mutiny in their headquarters in Dhaka last week, disgruntled over pay and other working conditions. The Bangladesh army says 56 officers were killed along with bystanders, civilians and other regular army troops. Officials say seven army officers are still missing.
Ms. Hasina has been praised for her swift reaction to the mutiny which caused chaos in the capital. Tanks rolled through the streets of Dhaka and officials quickly reestablished control of the guards' headquarters.
