Discription of Events: Got off work late at night entering the 101 from 91st and olive,to get on the freeway its 2 lanes and it merges into one as you match speed with the freeway. They were far behind me in the other lane, and at the last second they attempted to force themselves infront of me by speeding up VERY fast when there was someone infront of me, the lane had already began to merge into one so it was too late and they even tried driving around me but they couldnt obviously...I turned my left turn signal on, aswell as the person infront of me, however they swerved through the gore section illegally and then zoomed passed us. I got into the middle lane, and then they swerved right infront of me and I had to hit my breaks hard. This is where it gets weird! They proceeded to follow me the entire way. Every single move I made, they swerved infront of me to do the same and make sure they were going where I was going. They cut infront of me and wouldnt allow me in any lanes, they continously swerved out infront of me and hard break checked me to the point they were going 20mph on the freeway at night with no one infront of them. Finally at one point they switched lanes and matched speeds with me. There were two people flipping me off out the window, making strange gestures and almost swerving into my truck several times. I got off the freeway early, on thunderbird, and they swerved infront of me illegally to go off on the same exit and they went extremely slow all the way off the exit. Every single turn I made, they made and kept break checking me and making gestures out the window, so I took down the license plate quickly and called the police. This continued all the way to 91st and tbird. At the last second, I switched lanes all the way over to the far left to get away from them as they thought I was going to turn right on 91st and thunderbird, down near desert harbor/harbor island. They had pulled over and was watching me from a distance, and then drove off extremely fast. I believe these people wouldve tried to cause harm to me as they were being extremely reckless out of nowhere and making gestures. I dont recognize this vehicle, and I have no idea who was in the car. It appears that it may have been a white male and female but Im not sure. This was at 11pm on 2/8/19, in Peoria Arizona.
