Detective Branch (DB) of police has arrested seven alleged criminals, including a woman, in two separate raids in the capital, and seized five foreign pistols and six kilograms of explosive materials from their possession.
The drives were conducted on Monday night and on April 28.
The arrestees are Mohammad Kabil, Jinnur Rahman alias Jillur, Rakibul Hassan, Nizam Uddin, Saddam Hossain, Shariful Islam alias Ashraful Islam and Khaleda Begum.
Of them, Kabil, Jinnur and Rakibul were nabbed along with three pistols and 15 bullets from the capital's Jatrabari on Monday night, said Krishna Pada Roy, deputy commissioner of DB (South).
At a press briefing at the media centre of Dhaka Metropolitan Police yesterday, the DB official said its newly formed anti-kidnapping squad members detained the three based on information from eight fake DB members, who were arrested in the capital's Aftabnagar on Sunday night.
The three used to supply arms to the fake DB members, who allegedly abducted people for ransom, identifying themselves as law enforcers.
After primary interrogation, Krishna Pada said there were several other fake DB gangs in the capital and its adjacent districts, who received the arms from the three.
The trio was assigned to send the arms to Comilla, DB officials said.
In another drive on April 28, detectives held Khaleda and three other criminals along with two pistols, 13 bullets and six kilograms of explosives in the Farmgate area.
Khaleda confessed to the DB officials that she usually carried arms on her body.
DB officials suspect there are other gangs who also use women as carriers as it is apparently easy for them to carry arms more safely than their male counterparts.
Contacted, Assistant Commissioner of DB Jahangir Alam, who led both the drives, said the two gangs used the Chapainawabganj border to smuggle arms into the country from India.
They used to sell or rent the arms to other criminals. But they did not use the arms themselves, he mentioned.
