REDMOND, OR -- Two teens were assaulted at Hope Playground in southwest Redmond, Saturday night. According to Police, two men wearing bandanas on their faces attacked the 15- and 16-year old boys with brass knuckles and a box cutter at about 7:25 p.m.

The victims ran to a nearby McDonalds and called for help and one was taken to the hospital with non-life threatening stab wounds. Police conducted an extensive search of the area and reviewed video surveillance of the park. They say information gathered during that investigation led them to Redmond 18-year-olds Isiah Laack (Pictured, right) and Noah Huber (left), as well as a 15-year-old boy from Bend.

All three suspects were found and questioned at a Redmond home prior to their arrest. Laack is accused of using the brass knuckles and charged with Assault, Unlawful Use of a Weapon and a Parole/Probation Violation, among others. Huber is believed to have had the box cutter; he also faces a list of charges, including Assault, Tampering with Evidence, Disorderly Conduct and a Parole/Probation Violation. The younger suspect was arrested for Assault III, Unlawful Possession of a Weapon and Disorderly Conduct.

Investigators say the suspects did not know the victims and believe it was an unprovoked attack.
