Two youths supposedly threw a "black bag" at a security guard of the embassy following an altercation and ran away. Later, the bomb disposal unit of Counter Terrorism and Transnational Crime (CTTC) unit found a match box, a cup wrapped with black tape, some wire and a knife inside the bag. Law enforcers today said that the whole episode was staged by embassy security guard Zakir Hossain Mollah, who apparently did it for reward.
