Two bike patrol officers shot and wounded a man witnesses say threatened people with a rifle near Occupy Houston's camp on Monday.
Police said the shooting occurred at 5 p.m. in Tranquility Park in downtown Houston after a man with a .40-caliber rifle refused to drop his weapon.
Police spokesman John Cannon said the officers struck the man twice with gunshots, including at least once in the ankle.
Cannon said the man was conscious when he was taken away by ambulance. The 21-year-old man had injuries requiring surgery but were not believed to be life-threatening, the Houston Chronicle reported.
No one else was injured.
Witnesses told the Houston Chronicle that the man entered the park shooting the weapon. But he did not appear to be targeting the Occupy Houston camp because he walked past it on his way to a pedestrian bridge.
Occupy demonstrator Tim Jones told the newspaper that the witnesses did not think the rifle was real until the man fired into the reflecting pool under the bridge.
Several campers told the newspaper that the man was not part of the movement and that they hadn't seen him before.
