Dhaka: Bangladesh Nationalist Party (BNP) Chairperson Khaleda Zia on Sunday night alleged that party's assistant organising secretary Nasiruddin Ahmed Pintu was killed at the behest of Prime Minister Sheikh Hasina.

‘I want to clearly state that Pintu has been killed and a trial of this murder must be held. Hasina and others involved in the murder won't be spared,’ she said while exchanging greetings with the Buddhist community members on the occasion of Buddha Purnima at her Gulshan office.

The BNP chief questioned as to why the jail authorities did not ensure Pintu's treatment as per a High Court order.

‘We know nothing happens without Hasina's order. Pintu was taken to Rajshahi jail from Dhaka at her behest. So, she is responsible for the killing,’ added Khaleda Zia.

At the beginning of her speech, the BNP chairperson expressed deep shock at the death of Pintu and termed him a dedicated and tested leader and organiser.

‘But Pintu died without proper treatment in prison. We've heard that a doctor went to the prison to treat him but he was not allowed to enter the jail. Will you call them human being? They're actually devil,’ said BNP chairperson.

She alleged that though Pintu was an MP the authorities were not allowing to hold his namaj-e-janaza at the South Plaza of parliament as per tradition.

Referring to the disappearance of BNP joint secretary general Salahuddin Ahmed, Khaleda said the law enforcers picked him up.

‘We want to know, where's Salahuddin? Return him to his family unharmed. No one will be spared if anything happens to him,’ she warned.
