Thousands of volunteers have taken to the streets of Detroit to guard against a recurrence of the traditional Devil's Night arson spree.
So far, a spokesman for Mayor Ken Cockrel Jr. says fire reports are at or below last year's level for the two days before Halloween.
Daniel Cherrin says a "great community effort" is keeping the city safe. He says an accident and not arson caused a house fire that killed a man and woman Thursday night.
Detroit authorities have designated the anti-arson effort as Angels Night. It includes a youth curfew as well as citizen patrols.
Authorities in Benton Harbor, Flint and Saginaw also say the situation was calm in their communities Thursday night.
