In the meantime, the Indonesian Police Headquarters raised the national security alert to the highest level in line with the KPU declaring the election results in the wee hours of Tuesday.
"That is right that information was received from the National Police Chief's Operational Assistant, Inspector General Martuani Sormin, that today, Alert 1 has been issued," Brigadier General Dedi Prasetyo, spokesman of the Indonesian Police, remarked.
Moreover, the regional police are required to maintain vigil and take necessary precautionary measures if the need arises.
