The prime accused in the case Zahida Pervez, Saba Farooqui, Shaqib Ali (danger) Irfan and Tabish are likely to be produced before Special CBI judge Shubra Singh.
CBI had arrested Zahida, Shaquib and Saba after scrutinising call details generated from the tower located in the Koh-e-Fiza area where Shehla was shot dead in front of her house on August 16 last year.
Later CBI arrested Iran and Tabish in the case from Kanpur.
It was alleged that Zahida ordered the killing of Shehla as she was jealous of her purported closeness with BJP MLA, Dhruv Narayan Singh.
CBI had questioned Dhruv and also called him for conducting his polygraph test.
According to CBI, Zahida had allegedly hired contract killers through Shaqib to eliminate Shehla and had also maintained a diary of events that took place after her sensational murder.
