According to the police report, a woman called 911 from a home in the 10000 block of 18th Place SE in Lake Stevens around 10:18 p.m. The woman said her husband, who had been drinking, "shoved her down and kicked her," the report said.
About 10 minutes later, a man called 911 from the same home and said no assault had taken place. He added his wife had been drinking.
When deputies arrived, both the woman and her husband appeared calm. The 41-year-old officer said he had taken a dose of the sleep aid Ambien a short time ago, and was preparing for bed. He denied that any assault had taken place.
However, his wife said the couple had had an argument that had escalated. The woman, who is scheduled to move out of the home on Saturday, told investigators her husband "became very angry and grabbed her shoulders with each hand and violently pushed her back so hard she fell backwards on the floor." The woman said she "feared that it may escalate to worse," the report said.
But the officer told deputies he had not pushed his wife; he said she had either slipped or fallen because she was intoxicated. He said the incident was "seemed so ridiculous" that he burst out in laughter, angering his wife who then called 911.
The officer was booked into Snohomish County Jail for investigation of fourth-degree assault, domestic violence.
Seattle Police Department's Office of Professional Accountability has launched a review.
The unidentified officer, who was assigned to the Special Operations Bureau, has since been reassigned to his home pending the outcome of the investigation.
