The National Investigation Agency (NIA) would again take the two arrested Maoists who were involved in the May 25 Chhattisgarh Maoist ambush, on a five-day remand, said police sources.
After completion of the first remand period on Tuesday, the three-member NIA team has requested a local court in Malkangiri to take the duo for a second phase of remand for further investigation.
During the first remand, the NIA team had asked details about the two hardcore Maoists, Kasa Madhi and Ura Madhi of Katamateru area in Malkangiri, who were arrested on June 25 during a combing operation.
The arrested ultras had revealed before the team that they had been imparted training for the big attack along with other 35 Maoists from the State. The team was happy over obtaining a few secrets from the Maoists.
Meanwhile, the Malkangiri police detained two other persons suspecting their involvement with the Maoists.
