Who exactly were these UK troops training before? The Guardian:

Members of the Rapid Action Battalion (RAB), which has been held responsible for hundreds of extra-judicial killings in recent years and is said to routinely use torture, have received British training in “investigative interviewing techniques” and “rules of engagement”.

Details of the training were revealed in a number of cables, released by WikiLeaks, which address the counter-terrorism objectives of the US and UK governments in Bangladesh. One cable makes clear that the US would not offer any assistance other than human rights training to the RAB – and that it would be illegal under US law to do so – because its members commit gross human rights violations with impunity.

Since the RAB was established six years ago, it is estimated by some human rights activists to have been responsible for more than 1,000 extra-judicial killings, described euphemistically as “crossfire” deaths. In September last year the director general of the RAB said his men had killed 577 people in “crossfire”. In March this year he updated the figure, saying they had killed 622 people.
