State police say he choked her unconscious and trapped her in a bedroom for hours by threatening to abuse her again if she tried to escape from their home in Gordonville, a tiny village with a strong Amish presence an hour's drive west of Philadelphia.
Trooper Samuel Laureto says the woman was hit in the head and arm Saturday morning and suffered a broken elbow in an unprovoked attack.
Police say she escaped when the man left and she went to a neighbor's house to call for help.
She told police the man smoked crack cocaine while assaulting her.
The man was arrested the next day at a relative's home. He's charged with assault and unlawful restraint.
