(WBIR - Newport) A Cocke County man whose family received a new home built by volunteers is now behind bars and facing arson charges.

Newport police arrested Tony Williams Monday on three counts of aggravated arson, one charge of setting fire to personal property, and one charge of coercion of a witness.

Police say Williams is accused of setting three vehicles on fire. The fire also damaged a nearby home.

You may recall almost two years ago, community members built Williams' son Brandon a 1,200 square foot home after the boy lost both ears in a pit bull attack. More than 200 volunteers from the community worked on the home to help the two move past the incident.

Investigators have not mentioned a motive for the criminal charges.

Williams is in jail and being held on a half a million dollar bond.

His son, Brandon, is staying with his grandparents.
