The shooting incident reportedly occurred at the Ceylon Petroleum Corporation (CPC) premises in Dematagoda, reports said.

According to police, a tense situation had occurred when a group of protesters had obstructed when the former Minister of Petroleum Resources Development Arjuna Ranatunga arrived at the premises of the CPC this evening, reported Daily Mirror of Sri Lanka.

Police told the newspaper that a security personnel of the minister had fired shots at the protesters.

The three injured people have been admitted to Colombo National Hospital.

One security personnel has been arrested.

An investigation into the incident is currently going on.

Political crisis in Sri Lanka:

This was the first incident of violence since Sri Lanka President Maithripala Sirisena on Friday sacked Prime Minister Ranil Wickremesinghe and appointed former president Mahinda Rajapaksa as the new premier.

Rajapaksa was sworn-in on Friday itself.

Relations between Sirisena and Wickremesinghe's political parties, who have governed in coalition since 2015, received setback since both suffered humiliating losses in February's local council elections.

According to reports, they have clashed in cabinet last week over government plans to lease a container terminal to neighbouring India.
