Sabikunnahar, wife of Islamic Preacher Abu Taw Haa Muhammad Adnan who has been missing for the last four days, sought Prime Minister Sheikh Hasina's intervention in finding her husband.
In a letter addressing the prime minister, Sabikunnahar said her husband could not be traced for the last four days.
No legal assistance was found even after visiting Darus Salam and Pallabi police stations, Sabikunnahar claimed.
"After being failed to get help from others, I am praying to you as the last resort to get my husband back," the woman urged the PM, addressing her as mother.
On Thursday, Adnan along with his two associates and a driver went missing while they were returning to Dhaka from Rangpur in a rented car.
