In Osogbo, Osun State, an elderly woman identified as Sariyu Akanmu, was brutalised by policemen while 10 members of the #RevolutionNow were arrested.
The police had asked the protesters to disperse but the youth, numbering about 30, decked in orange beret and handkerchiefs, stood their ground and sang protest songs for about two hours.
The security men later seized their public address system and ordered them to fold their banners.
This led to a clash between the police and the protesters.
The police descended on the protesters, beat them up, before firing tear gas canisters to disperse the crowd.
In the ensuing melee, Sariyu, who is about 70 years old and sells fufu, was brutalised by a policewoman, while another policeman hit her with his footwear.
Journalists and many bystanders were also not spared, as a police woman released tear gas canister into the face of Sunday Oguntuyi, the correspondent of Nigeria News Direct newspaper.
Some members of the #RevolutionNow group were also brutalised by the DSS operatives, while about 10 members of the group were arrested.
Addressing newsmen earlier, Olawale Adebayo, who led the protest, demanded unconditional release of Sowore.
