Dudh Mia, joint convenor of Meghna Upazila Awami League, was killed in a crossfire with Rab in May.

Dudh Mia's wife Begum Kawsary Islam at a press conference told the journalists that JCD and Jubo Dal cadres ransacked the chehlum venue at Shayesta Khan Welfare Centre at Lalbagh in the city at the order of BNP lawmaker Nasiruddin Ahmed Pintu. She demanded immediate arrest and trial of the cadres involved in the act.

"A gang of 20 to 25 BNP, JCD and Jubo Dal cadres led by ward commissioner Babul's brother Sharif, Jubo Dal leader Rafiq and Lalbagh Thana JCD President Sayeed Hasan Mintu damaged rice, pulse, spices and meat for the chehlum," she said.

Dudh Mia's wife said local Jubo Dal also arranged a meeting at the same venue. Former Awami League lawmaker Haji Selim said lawmaker Pintu attended the programme as chief guest.

The press conference was held at the Dhaka Reporters Unity's (DRU) auditorium.

Kawsary Islam said that she booked the community centre for the programme on June 1. "But lawmaker Pintu threatened from a Jubo Dal meeting in Lalbagh on June 6 of spoiling our programme at any cost and asked local JCD and Jubo Dal men to carry out his order," she added.

She demanded exemplary punishment to the perpetrators.

"We have decided to file a case with the court as the local police refused to register any case in this connection" she said.

"I filed a general diary with Lalbagh police station on June 5 for safety, but police did not take any step in this regard," she said.

Dudh Mia's father Azimuddin, mother Alimunnesa, son Johnny, daughters Beauty and Seema were also present at the press conference.

BNP MP Pintu could not be reached over phone for his version despite several attempts yesterday.
