Charleston - Huntington, West Virginia -- WOWK -- 13NewsLogan fire ruled arson

A fire that devastated at least four buildings in downtown Logan earlier this week has been ruled arson.

The blaze damaged at least four buildings in the downtown district early Wednesday morning.

It started at a former law office that's been vacant for months.

Witnesses say three men were seen leaving the building that burned, and the front door was open when firefighters arrived.

A Logan fire department investigator is asking anyone who has information about the fire to call the Arson Hotline at 800-233-FIRE.
