A heavy police presence filled an intersection in the Ruby Hill area of west Denver.
Denver Police haven't commented much on the situation but say one person was transported from the scene in the 1400 block of West Mississippi.
The nature of that person's injuries is unknown.
Denver7's Marshall Zelinger went to the scene. He says at least a dozen Denver Police cars were there.
