One individual was arrested by police early this morning and later, another had surrendered.
The two suspects were found to be residents of the area and police said they had been under the influence of alcohol when the incident occurred.
The Samagi Jana Balawegaya (SJB) leader was addressing the meeting when someone had hurled stones in the direction of the stage.
Immediately responding to the stoning, Premadasa stated he would not leave just because stones are hurled and everyone is well aware who steered politics in Rathmalana.
“I will not leave because stones are pelted. I am not afraid. I will not leave in fear of any thugs. Therefore, I am ready to face any challenge," he said.
