For over a month, citizens have been protesting across Sri Lanka, demanding the resignation of President Gotabaya Rajapaksa and his prime minister brother, Mahinda Rajapaksa, whom they blame for the country’s worst economic crisis.

The prime minister resigned last week, after supporters of the Rajapaksas attacked demonstrators in Colombo. The violence left nine people dead and wounded nearly 300, leading to days of unrest.

So far, two Sri Lankan ruling party lawmakers have been arrested on charges of involvement in attacks on anti-government protesters, a top police official said on Wednesday.

Sanath Nishantha and Milan Jayathilake were among 22 politicians -- including former prime minister Mahinda Rajapaksa and his son Namal -- whose passports were impounded last week following allegations that they instigated the violence.

The two lawmakers from President Rajapaksa’s Sri Lanka Podujana Peramuna party were arrested, after a criminal investigation, on Tuesday evening and have been remanded by the Colombo Fort Magistrate’s court until May 25.

“As a result of the investigations, the detectives arrested SLPP MPs Milan Jayathilake and Sanath Nishantha on Tuesday,” Senior Superintendent of Police Nihal Thalduwa said.

He added that another four high-ranking officials were also detained “over their involvement in the attacks on the ‘Gota go gama’ and ‘Myna go gama’ peaceful protest sites.”

“Gota go gama” and “Myna go gama” are popular slogans among protesters. “Gota” is a reference to President Rajapaksa, while “Myna” to his ex-PM brother. The “go gama,” literally “go village,” is a call on them to leave and go home.

Thalduwa said 883 people have been arrested over the violence that shook the island nation between May 9 and May 11, leading to the deployment of troops in many parts of the country to impose a curfew that was only lifted on Wednesday morning.
