SNOHOMISH, Wash. (AP) – Authorities used an armored vehicle to smash through a wall of a Washington state house to end an eight-hour standoff with an armed man.

KOMO-TV reports the man locked himself inside the Snohomish house Sunday after deputies responded to a report of a man shooting at his ex-girlfriend.

The Snohomish County Sheriff’s Office says the woman escaped the house uninjured.

A SWAT team fired tear gas and pepper balls into the home after negotiations failed.

Deputies later entered the home with a police dog after the BearCat armored vehicle broke through.

Authorities say the man was taken to a hospital for treatment of dog bites and other minor injuries.

The sheriff’s office says he will be arrested on suspicion of domestic violence assault and unlawful possession of a firearm.
