A Scarsdale police officer is suspended with pay after he was arrested in Elmsford.
Village police say 30-year-old Dante Barrera was charged with second-degree assault for an incident at his home last month.
He allegedly hit a 30-year-old woman in the leg with a metal hammer.
It's unclear how they knew each other.
Barrera, an officer for two years, was arraigned in Village Court and released on his own recognizance.
