A Ladson man was arrested Monday after his wife found out he was already married.

Michael Dean Duncan, 32, faces a felony bigamy charge.

Duncan married a Moncks Corner woman Dec. 20, in Asheville, N.C., according to Buncombe County Sheriff's Office spokeswoman Natalie Bailey. His wife learned that Duncan was already married through his first wife's attorney. The second wife and Duncan were living separately by then.

The first wife, who is from Summerville, had an attorney because she and Duncan were separated and involved in a custody battle over a small child, Bailey said.

When the second wife learned that Duncan was already married, she called the sheriff's office in North Carolina, since that's where they were married.

Duncan was booked into the Buncombe County Detention Facility and released on $5,000 bail.
