Homeless man arrested for fire near Hwy 4 in Concord

A homeless man was arrested on suspicion of starting a fire near Highway 4 in Concord early Wednesday morning, authorities said.

Authorities told KTVU that the man started a fire in a building he was living in, and the flames then quickly spread to a nearby field.

Fire crews were called to the Willow Pass Road on-ramp to eastbound Highway 4, just before 3 a.m.

No injuries were reported for either the building or brush fire.

As of 4:45 a.m., the on-ramp remained closed, and there was no official word on when it would reopen.
