Police arrested a 23-year-old Federal Way man after he allegedly stabbed his father multiple times and fled the scene on Saturday night.

Federal Way police responded to the stabbing at 7:53 p.m. in the 32000 block of 14th Ave. SW, where the 50-year-old victim reported that his son stabbed him in his back, head and chest with a large knife.

The father was transported to Harborview Medical Center, where he had surgery and remains in serious condition, according to Federal Way police spokeswoman Cathy Schrock.

A family member told police she saw the son fleeing the residence carrying a type of knife/sword with blood smeared on him, according to the police report.

Officers later located the man approximately four blocks away and arrested him. Charges are pending for first-degree assault.

The report does not indicate the circumstances leading up to the stabbing, however, it notes that the son has suffered from “mental problems.”

The Mirror will update this report when more information becomes available.
