Jahangir Alam used to earn his living by selling scraps collected from street children in the capital's Chawkbazar.
Three months ago, however, the 45-year-old who did not even complete his school education was appointed the "chief chemist" of a factory manufacturing fake foreign liquor.
Jahangir used to make fake vodka and whisky in a factory on the second floor of a small building in the capital's Bhatara.
At least six people have died in the capital after drinking the whisky and vodka made by Jahangir, according to police's detective branch (DB).
A team of DB (Gulshan Division) police said they learned this information when they conducted a drive in Jahangir's fake foreign liquor factory late Monday night.
