Dhaka, Aug 24 (IANS) The trial of over 800 mutineers who were involved in the massacre of 74 people, including 57 army officers, at the Bangladesh Rifles (BDR) headquarters in Dhaka in 2009, began in the capital Wednesday.

The trial began with the deposition of a former officer-in-charge of the Lalbagh police station in Dhaka, the Daily Star reported.

A total of 847 people - including 824 BDR troopers and 23 civilians - have been accused in the Feb 25-26, 2009, carnage in Dhaka's Pilkhana area at the headquarters of the border security force.
