Police have already stated that Dayanand Patil, in whose carry bag, one of the explosives went off near Balghandharva Theatre, was not under detention or arrest and was being interrogated only to know details of the events leading to the blasts.
No headway has so far been made in the investigations a week after the explosions occurred.
A tailor by profession, Patil, who used to commute daily from the nearby Uruli Kanchan village to Pune to work in a shop, was treated for minor injuries and a spinal cord problem in the Sassoon Hospital here, from where he was discharged on Monday night, hospital authorities said.
Patil, however, was being taken to his native place Bidar in Karnataka by the ATS officials as part of the ongoing investigations into the blasts, sources said.
In view of the blasts, police have appealed to people not to congregate in large numbers on the streets for the 'Dahi Handi' festival to celebrate Janmasthtami festival tomorrow.
