The Joint Opposition (JO) protest ended last night with one man being reported dead and several taken to hospital.
Police spokesman SP Ruwan Gunasekera said that one person had died after suffering from a heart attack.
Gunasekera said that the man reported dead was a resident of Thalawakele and he had arrived in Colombo to take part in the protest.
The Police spokesman also said that several people had sought treatment in hospital last night from suspected food poisoning.
He said that while the actual number could not be confirmed yet, reports indicated that around 25 people had sought treatment at the Colombo National hospital.
Asked if there were any arrests, the Police spokesman said that no one linked to the protest was arrested.
He also said that there were no major incidents reported related to the joint opposition protest.
The protest ended prematurely last night despite a call by the joint opposition leaders for the protest vigil to continue till this morning.
Meanwhile, the road opposite Lake House was cleared this morning for vehicular movement after being partially closed from last evening as a result of the protest. (Colombo Gazette)
