Sector 1: Two men were arrested on suspicion of first-degree robbery May 6. The victim reported he went to the 900 block of South Grant Street to sell two men custom embroidered hats. The suspects pulled a gun and then took the hats and jewelry from the victim. University Place police found the suspects a short time later.

The community liaison officers have been working on identifying where fencing needs to be placed along the BNSF railroad tracks below Interstate 705. "This is aimed at stopping the encampments under Hwy 705 and eliminating the issues surrounding the Russell Building," the report states.

Sector 2: There has been an uptick in car prowls at several locations within Point Defiance Park. Speeding also continues to be an issue despite additional traffic bumps installed by Metro Parks.
