Additional police forces have been deployed at key point installations (KPIs) across the country including the capital Dhaka to ward off any sabotage during the power outage. 

Police units in the capital and elsewhere have been instructed to stay alert so that law and order does not go out of control, said an official at Police Headquarters seeking anonymity.

The whole country suffered power outages when the Bangladesh-India power interconnection line at Bheramara in Kushtia tripped.

The interconnection line used for transmission of 450 Megawatt power, tripped at 11:30am, a source at Power Development Board (PDB) told The Daily Star.

The sudden vacuum caused disruption of power generation at all power plants across the country.

Around 1:00pm, some power plants resumed generation.

Officials concerned expressed their hope that the power general will be restored by tonight.
