The mother of dentist Ahmed Mahi Bulbul has sought the intervention of Prime Minister Sheikh Hasina to bring the killers of her son to book.
Bulbuli Begum, the mother of the doctor, said this at a press briefing at their house in Rangpur on Monday.
She also demanded that the prime minister bear the expenses for raising her two children.
Some of his friends were present at the briefing. They said Bulbul was a doctor for poor people.
Law enforcers should investigate the case with the utmost importance, they said.
Meanwhile, the body of the doctor was taken to his native village of Bhogibalapara on that day and buried there.
Earlier on Sunday morning, some miscreants stabbed the dentist to death at Shewrapara in the capital. Police suspected that muggers might have killed him. His wife filed a case with Mirpur Model Police Station in this regard.
