"We have enough evidence to prove he had connections with underground Maoists and that he acted as a link between the CPI (Maoist) and urban Maoist sympathisers," Kadam said.
Saibaba will be brought to Aheri in Gadchiroli district by Friday night or Saturday morning, Kadam added.
The Gadchiroli police had questioned Saibaba for at least four hours this January, confronting him with evidence found on his computer that was seized during a raid at his Delhi residence.
Kadam said the policy documents and strategy papers of CPI (Maoist) were recovered from Saibaba's computer.The professor's name came up after the arrest of two alleged Maoist sympathisers, Jawaharlal Nehru University (JNU) student Hem Mishra and activist Prashant Rahi.
Mishra and Rahi were arrested by Maharashtra Police in Gadchiroli a few months ago. Both had reportedly claimed that Saibaba was their main contact. The Gadchiroli police then raided Saibaba's house.
Mishra, who was arrested with a microchip, said he was passing on instructions to Maoist leaders holed up in Abujhmad forests in the tribal regions of Gadchiroli and Chhattisgarh's Bastar.
