The demo on Thursday was organised by HRDC, who gave a petition to Police demanding immediate action against the alleged perpetrators.
Police intervened several times to calm the situation and ended up arresting 17 unruly characters, Police spokesman James Kadadzera said, adding that reports they had received were that five shops and five vehicles were vandalized.
Police have instituted a probe after it emerged that they raped the females at Nsundwe, apparently in revenge of the stoning to death of their colleague by roughness at the trading post along Lilongwe-Mchinji road.
Up to a dozen protestors from Nsundwe have been arrested.
The government funded Malawi Human Rights Commission said in its report 17 girls and women were sexually abused.
HRDC has been in the forefront organising demos against MEC for alleged electoral irregularities last year.
This was the first time for HRDC to march against Police.
A preliminary Police report on Thursdays march says six police officers were injured by the unruly crowd, while shops of Mapanga Furniture and Blockbuster, Mchesi Rising Star, Newton Hardware and Chimbwabwa Funeral Service at Mchesi were looted and damaged by the demonstrators.
