Officers got a 911 call around 4:30 a.m. from the suspect's mother, stating her son had come over to their home in the 10400 block of 57th Ave. S., demanding money from his father, said Det. Renee Witt with Seattle Police.
The man was armed with an ax and struck their front door several times, Witt said.
As police were responding, officers were notified the man had left with his father in a car and was now armed with a gun.
Officers found the father at 56th Ave. S. and S. Bangor Street. He told the officers his son showed a gun and told him to drive to the Safeway on Rainier Avenue and get $400 in cash, although no money actually changed hands.
The father then dropped his son off on S. Bangor Street where he walked to his grandparents' home in the 10700 block of 56th Ave. S., Witt said. Police believe the son was still armed with the gun at this point.
Officers surrounded the home and eventually convinced the man to surrender peacefully. No one was hurt.
Witt says the suspect's grandparents denied knowing that the man was armed and declined to allow the officers to search their home for a weapon.
The suspect is a convicted felon with a lengthy criminal history, and SPD SWAT has contacted him at the 56th Ave South location on a prior occasion, Witt said. He was booked into the King County Jail for investigation of Attempted Robbery and Unlawful Imprisonment.
