Lowell Turpin. (HO, Anderson County Sherriff's Office)

A 40-year-old Tennessee man accused of domestic assault allegedly became enraged when he saw a picture of a strange man on his girlfriend's Facebook page and suspected she was planning an affair — he apparently didn't recognize presidential hopeful Mitt Romney.

Lowell Turpin, 40, "angrily demanded to know who the male was," according to a police report cited by the Knoxville News Sentinel.

When she told him, he allegedly grabbed her laptop and smashed it into a wall, then punched her, the police report says.

Turpin remains in custody.
