MUKILTEO, Wash. (AP) — Washington state troopers say they arrested a man who carried a semi-automatic rifle aboard a ferry in Mukilteo. The man walked onto the M/V Tokitae around 7:43 p.m. Wednesday as passengers boarded for a trip to Whidbey Island. Ferry workers called authorities when they saw ammunition partially concealed on the man. The captain held the vessel at the dock, while the man entered a restroom. Troopers found the man’s “AR-15 style weapon” was partly or fully concealed. He was escorted off the ferry and booked into Snohomish County Jail for carrying a concealed weapon without a concealed carry permit.
