Two Thornton, CO, police officers were hospitalized Friday during a struggle with a man accused of shooting up heroin at a park. One officer suffered minor injuries; the extent of the second officer’s injuries was unknown, reports KMGH.

Jason Masek, 22, is behind bars facing a long list of charges after allegedly escaping custody twice during the arrest.

Around 10 a.m., Thornton officers were called to the park in the 800 block of Croke Drive on a report the suspect was using the drug. When they arrived on scene, police say Masek fled into a nearby library where a struggle inside the building's bathroom led to the officers’ injuries.

Police say the suspect escaped after the bathroom attack but was later spotted nearby by another Thornton officer and taken into custody. He was taken to the hospital where police say he managed to escape a second time. But police had him in custody again after a short foot chase.
