UPFA politicians Upali Kodikara, Sampath Athukorale and Ajith Prasanna have been asked to appear before the Hambanthota Police today in connection with the anti-Indian protest in Hambanthota, last Friday.
Police sources said statements would be recorded from the MPs over their involvement in the protest which was held despite a court order.
The protest was led by Joint Opposition MP Namal Rajapaksa.
Police arrested 26 Joint Opposition supporters for taking part in the demonstration in violation of a court order.
The protesters demanded the government to refrain from leasing out the Mattala International Airport to an Indian company.
