Multiple REDDI (Report Every Dangerous Driver Immediately) callers helped police arrest a woman who Anchorage Police say was driving over two times the legal limit with an infant inside.

On Tuesday at 4:41 p.m., several REDDI callers reported seeing a silver Ford Focus driving inbound on the Glenn Highway from Valley. The callers said the car was driving without its headlights on and couldn't stay in its lane for prolonged periods of time. Police say at one point, the vehicle drove into oncoming traffic. 

About two minutes later, the Alaska State Troopers starting getting calls about the same vehicle.

"AST reported they had received citizen complaints reporting the vehicle was alternating between the speeds of 40 and 80 mph and had hit a cement sign before crossing over the Knik River Bridge into APD jurisdiction," APD wrote in a statement. 

At approximately 4:50 p.m., Troopers caught up with the vehicle in a ditch near North Peter's Creek Exit and took the driver, 21-year-old Deja Harris-Walker, into custody.

Police reported Harris-Walker gave a false name at first because she had an outstanding arrest warrant. 

Troopers learned after a field sobriety test she was over two times the legal limit and arrested her for operating over the influence. 

Harris-Walker was also driving with her 1-year old child in the car. Police say the infant was in a child seat but was not secured properly.

Relatives were unable to pick up the child, so it was taken to the Office of Children Services.

Anyone who believes they see an intoxicated driver is asked to "Report Every Dangerous Driver Immediately" by calling 911.
