Four senior British police officers arrived in Dhaka on Wednesday to investigate a killing spree by rank-and-file soldiers in the Bangladeshi capital that killed 74 people.
The officers from London's Metropolitan Police will offer Bangladeshi law-enforcement authorities expertise in dealing with "complex investigations," according to a statement from the British High Commission in Dhaka.
"Scotland Yard is at the cutting edge of criminal investigation. I am glad that we can offer Bangladesh this assistance at this time," British High Commissioner in Dhaka Stephen Evans said in the statement.
Fifty-six senior army officers were among those killed in the mutiny that broke out at the headquarters of the border patrol force, the Bangladesh Rifles, on February 25.
Since the 33-hour standoff ended, only a handful of suspected mutineers have been arrested, with an estimated 1,000 apparently fleeing in civilian dress.
The case has left Bangladesh in shock and has exposed deep tension between recently elected Prime Minister Sheikh Hasina and the country's military.
Two Federal Bureau of Investigation (FBI) officials from the United States arrived in Dhaka on Sunday to work on the case.
