Visakhapatnam: Banners and letters belonging to CPI (Maoist) Andhra Odisha Border (AOB) wing were found on Friday.
CPI (Maoist) party observes 'martyrs commemoration week' from 28 July to 3 August every year.
The letters alleged that police have been giving motorcycles and money to tribal youth to cover up their failures.
The letter further alleged that Visakhapatnam district police are carrying out false propaganda against Maoists. Tribals are being forced to do rallies and make posters in the name of anti-Maoist associations. Tribal communities are being persecuted by the police, the letter said.
