Tucson Fire crews pulled three people out of the Santa Cruz River during a swift water rescue Thursday afternoon.
A fourth person was rescued by a bystander.
According to Tucson Fire, crews were dispatched to the Santa Cruz River near West Prince Road at about 2:47 p.m.
The initial call was for two people and a dog stuck in a tunnel that emptied into the river.
They arrived to find two people and a dog stranded on islands in the middle of the river.
Crew members used a throw bag to rescue a third person and a dog from the water.
The Technical Rescue Team formed a wedge formation to walk into the river, which was above the knee and moving fast, to rescue the original two people and their dog, TFD said.
No injuries were reported, TFD said.
