Since the storm, people have broken into homes, malls and garages, where they have stripped the shelves of food, water and other goods. Authorities have struggled to stop the looting.
There have been unconfirmed reports of armed gangs of robbers operating in a systematic manner.
An 8 p.m. to 5 a.m. curfew was in place across the region. Despite incidents, police said the situation was improving.
“We have restored order,” said Carmelo Espina Valmoria, director of the Philippine National Police special action force. “There has been looting for the last three days, but the situation has stabilized.”
