The Sri Lankan government has been accused of a draconian crackdown on protesters who were involved in toppling Gotabaya Rajapaksa as president, with activists facing intimidation, surveillance and arbitrary arrest.

Dozens of protesters have been detained by the police in recent days as the government, led by the newly appointed president, Ranil Wickremesinghe, tried to crush the mass protest movement that forced Rajapaksa to flee the country and resign in early July.

After the fall of Rajapaksa, the protest movement, known as the Aragalaya, has turned its focus to Wickremesinghe, calling for him to step down. He is accused of lacking legitimacy and public support and of protecting the powerful Rajapaksa family, who are accused of bankrupting the country.
