Jatiyatabadi Juba Dal central leader Md Newaz’s home was raided at the wee hours of Wednesday, said Additional Deputy Commissioner of police Abida Sultana.
Seventy-four handmade bombs and a large quantity of explosives were found in the house in Lalbagh, she said.
Newaz, a Juba Dal joint secretary general, was not at home at the time of the raid, but police detained two people.
Incidents of arson, vandalism, and bombing have been reported from across the country since Jan 5.
The BNP-led alliance began an agitation that day, demanding snap polls under a ‘non-party’ government.
Over a hundred people have died so far —mostly due to firebombing of vehicles — in the 20-Party alliance’s transport blockade and general strikes.
