Grants Pass, OR) -- Police say they've arrested three teenagers in connection with a water beads assault on a girl in Grants Pass. Police arrested the teens last week for the assault earlier this month. Water beads are filled with gel and explode on impact when they're fired from a "Blaster" style gun. The girl had several injuries on her back. The boys were 16-, 15-, and 13-years-old. They're charged with assault, disorderly conduct and criminal conspiracy. A 16-year-old girl and an 11-year-old boy have charges pending.
