Be cautious and observe your surroundings:
On 21 November, in the Phoenix area, a woman was driving when she observed red and blue lights behind her so she pulled to the right and stopped. She noticed the motorcycle with the red and blue lights was a light colored sports motorcycle and the driver was wearing blue jeans and a blue T-shirt. The motorcycle operator was described as a white male in his late 20's with short light brown hair and "a few days growth" of beard. Further, the subject had a muscular build.
The subject approached the woman and requested her driver's license and registration. She confronted the subject stating he was not a police officer in uniform nor was his motorcycle a police motorcycle. The woman stated the subject became irate and ordered her to roll down her window all the way. The woman said she became more frightened and told the subject she would comply when they were at the police department and told the subject o follow her. The woman stated the subject followed her until she actually pulled into the parking lot of the local police department station then "the subject took off." She was unable to obtain the license plate on the motorcycle.
Stay safe.
