Scottsdale, AZ : Six people injured in a four-vehicle crash involved a PMT ambulance in Scottsdale on Sunday evening, Nov 1, 2015

About half-a-dozen people were injured in a four-vehicle crash in Scottsdale that involved a PMT ambulance Sunday evening, police said.

The crash occurred before 9 p.m. at the intersection of Hayden and Cactus roads.

A black passenger car was heading east on Cactus Road toward the Hayden intersection, officers said.

"It ran a red light at a significantly high rate of speed than is normal and a white passenger car was also northbound on Hayden," Scottsdale Police Sgt. K.C. Moore said.

Both vehicles collided.

The impact sent both vehicles crashing into the ambulance and an SUV, Moore said.

Police said two people were taken to a hospital with serious injuries and several others were less seriously hurt.

“We have witnesses who estimated the speed up to 80 mph," Moore said. Police were taking measurements to confirm that.

Police closed the intersection in order to clear the scene and investigate.

Moore said impairment has not been ruled out as a cause for the crash.
