A team of RAB 4 at first arrested Moni from Sighnbord area under Tongi upazila of Gazipur district early Monday following information extracted from JMB south unit Ameer Mahmudul Hasan who had been arrested on July 21.

The following morning, RAB, according to Moni's confession, picked up Oishee from her residence in Moghbazar area.

Later, another team of the unit detained Mou and Meghna from a house of Janata Housing in Mirpur 1 on Monday.

The RAB commander said one year ago, Hasan had directed Moni to form the female unit and one of her friends, who is staying abroad, influenced her to joint the militant organisation. She confessed it to the police elite force as well during the questioning, Lutfor also said.

RAB suspected that the formation of the unit is in the initial stage and they had been analysing its shape.
