There was no "international" pressure on the Bangladesh interim govt. at all. Godi Media Indian lies all.
These people (suspected perpetrators of the incident) were arrested immediately, the day after the incident based on CCTV footage. They will go through and the bear the full weight of legal scrutiny and prosecution per the legal framework in Bangladesh.
Indian govt. Godi Media propaganda is something else.
Bangladesh is a society that firmly believes in law and order, unlike current regime in India who believe in using 3rd rate tactics like using Hindutva goondas and mobs to intimidate foreign consulates and high commissions, as opposed to discussions and diplomatic foray.
