Cathy Schrock of the Federal Way police said the first incident took place Saturday at about 5:20 p.m. as an 8-year-old girl was crossing the playfield at the school, located at 3601 SW 336th St.
The girl told authorities a Hispanic man between 30 and 50 years old approached her and asked if she wanted candy.
The victim told the man "no" and attempted to run away but stumbled. The man followed the girl, grabbing her from behind when she stumbled.
When the man grabbed her, the girl scratched and bit both of his hands, causing him to let go of her and allowing her to escape, Schrock said.
With the assistance of the victim, a composite sketch of the suspect was completed. He is described as wearing a "reddish-purple" baseball hat worn sideways, a red bandana around his neck, a blue T-shirt, tan-colored tight pants and black shoes. The bandana worn by the man had a similar pattern to the one pictured above.
The second incident took place on Sunday at about 11:30 a.m. as a 7-year-old boy was walking in the approximate same location as the first incident.
The boy told police that a man of a similar description tried to grab him. The man then fled the area on foot.
Officers searched the area with a K-9 police dog, but did not find the suspect, Schrock said.
Both incidents are still being investigated and evaluated by detectives to determine if the two cases are related. Surveillance video also is being reviewed to see if the suspect was caught on tape.
