The unrest spilled into diplomatic territory when protesters hurled bricks and stones at the residence of the Assistant Indian High Commissioner in Chattogram around 1:30 am.
Though no damage was reported, the attack marked a serious escalation.
Police responded with tear gas and baton charges, dispersing the crowd and detaining 12 protesters. A few injuries were reported, and senior officials later assured the Indian diplomat of enhanced security.
The protests took on a sharply anti-India tone during a mourning procession on the Dhaka University campus, where supporters of the National Citizen Party (NCP) — an offshoot of Students against Discrimination (SAD) — accused India of sheltering Hadi’s attackers.
“They called upon the interim government to close the Indian high commission until they were returned,” witnesses said.
“The interim government, until India returns assassins of Hadi Bhai, the Indian High Commission to Bangladesh will remain closed. Now or Never. We are in a war!” said Sarjis Alm, a key NCP leader.
Former prime minister Sheikh Hasina, who fled Bangladesh after her ouster last year, remains in India — a fact repeatedly cited by protesters.
