Officers seized a gun, impounded two cars and arrested eight teens in the park Friday evening, and are now investigating possible connections between the teens and several burglaries and robberies, including two recent armed muggings.
The arrests came after police stepped up patrols around Roxhill Park in the wake of the robberies.
At about 4 p.m. Friday, patrol officers noticed a dozen teens milling around the area of the park where gunmen earlier had robbed two groups of middle schoolers of their cell phones and cash and hit two of the middle-schoolers with the butt of a shotgun.
When police approached the group of teens, several of them took off running. Officer were able to catch up to eight of the teens, who are all between 14 and 18 years old.
Officers arrested and booked one of them, an 18-year-old man, into the King County Jail for investigation of a weapons violation after police found a handgun and a box of ammo in the car he'd been driving.
Officers released the seven other teens at the scene, but police are now examining links between several of the teens and several robberies and burglaries in the West Seattle area.
Police also seized two cars from the park and are obtaining warrants to search the vehicles. At least one of the cars may be associated with a recent robbery case, police said.
