The 53-year-old soccer coach was with his teenage daughter outside Meadowdale High School Wednesday afternoon when the trouble started.
The man, who does not work for the school district, was waiting for members of his soccer team when three teenagers walked by and made what police describe as "deplorable comments" to his daughter.
Two of the three teens then attacked the coach before all three took off on foot. The man's daughter wasn't wasn't hurt, but the beating left the coach with cuts and bruises on his face.
The soccer team arrived moments later and called 911.,
Police say the main aggressor in the beating stands about 5'10" tall, weighs roughly 160 pounds and has shaggy blond hair. Police believe he is 15- to 17-years old. The second teen is about the same age, but had darker skin, short hair and angular features.
Anyone with information about the attack is asked to call Lynnwood police at (425) 670-5669.
