Police were dispatched to an apartment complex at 21st and Memorial for a different report, Wednesday afternoon.
According to Sgt. Ron Kawano, upon arrival, officers were reportedly flagged down by residents concerning a possible explosive in one of the apartments.
They reportedly went in and found an "improvised explosive device." As a safety precaution, they reportedly evacuated the building and called the bomb squad.
The bomb squad came on the scene, investigated the device and cleared all pieces as safe within the device.
Two residents were reportedly arrested, one for multiple warrants and the other was wanted by the US Marshal.
Everything was cleared around 6:00 p.m.
