BETHESDA, Md. (WUSA9) -- Montgomery County police have arrested a man who they say detonated explosives at his father-in-law's house in a domestic dispute.

Police say 36-year-old Marc Cassell was banging on his father-in-law's front door early Sunday morning, trying to get into his house, located in the 11400 block of Marcliff Road in Bethesda.

The father-in-law called police after he saw a large amount of sparks and smoke coming in the house and outside the front door. Cassell fled the scene in a car that was parked in front of the house.

When police arrived, they found an explosive device at the front door and another one near the garage that had caused significant damage. No one was injured.

Police say Marc Cassell and his wife are currently estranged and involved in an ongoing divorce and custody dispute.

Cassell was arrested in Fairfax County, Va. and is awaiting extradition.
