At 2:45pm a pedestrian flagged down a bicycle patrol officer to say he had been walking north when he was hit in the thigh by a long metal dart which penetrated his jeans and skin by approximately 1-2 inches.
As officers were speaking with the first victim, a second victim approached the group to say she had also been struck by a dart.
The victim was walking north on the east side foot path as well when she was struck in the knee cap by an identical dart.
Both victims were treated by paramedics and released at the scene.
The darts are made from a metal body approximately 5 inches long with one end sharpened to a fine point. The tail of the dart is topped with a white plastic cap which allows the dart to be from a blow gun.
