The city installed the fence because homeless campers were destroying the area and threatening neighbors.

Terry Shumway, a 20-year resident of the area, tells KOIN she is upset that the fence was torn down. Neighbors showed KOIN that even before the fence was destroyed, people had managed to still camp in the fenced off woods.

Police say they are investigating the vandalism.

“We are going to investigate the damage to this fence, it’s a pretty large scale vandalism,” Cptn. Claudio Grandjean tells KOIN.

Police are offering a $500 reward to anyone who has information about who damaged the fence.
