Mr. Mane was attacked with sticks by the group when he went to open his shop at Talegaon Dabhade.
The attackers fled the scene when people around raised an alarm, they said.
“He has sustained minor injuries and is out of danger,” Superintendent of Police (Rural) Pratap Degaonkar said, adding that the activist had refused police protection for the last two days.
Mr. Mane was given police protection after he received threats to his life in the course of his campaign under the RTI, highlighting various cases of irregularities and corruption, Mr. Degaonkar said.
Mr. Mane was an associate of RTI activist Satish Shetty, who was murdered last year in Pune. — PTI
