When one of the employees confronted him outside of the bookstore, he ran a few feet and then stopped. The employee then escorted the male back into the store and called police.

The student said he forgot his wallet at home and didn’t have the money to pay for the items, so he decided to steal them. He said it was a stupid thing to do and apologized to the officer.

An officer was driving eastbound on East University Boulevard when he noticed a vehicle speeding southbound on North Park Avenue at 12:15 a.m. Sunday.

The officer visually estimated that the vehicle was traveling over 40 mph in a 25-mph zone and witnessed the driver accelerate through the stop sign at the intersection at East University Boulevard and Park Avenue without stopping or slowing down.

The officer activated his lights and followed the car south on East Park Avenue and he witnessed the vehicle run through another stop sign. The vehicle then tailgated a truck for a short distance and attempted to overtake it by crossing over a double yellow line into oncoming traffic. The vehicle abruptly swerved back behind the truck and pulled over.

The officer approached the vehicle and asked for the two passengers to place their hands on the dashboard where he could see them. The passengers complied, and the officer noticed a case of beer on the floor. He asked the driver and passengers to provide identification and proof of insurance.

The driver nervously fumbled for his paperwork, saying, “”This is my roommate’s car. I’m borrowing it,”” according to reports.

The officer asked if he saw the stop signs he ignored and if he knew he was speeding. The driver replied that he knew he was.

The officer then pointed to the beer on the floor and asked what it was. According to reports, the driver replied, “”Officer, I’m not going to lie to you. I’ve been drinking.””

Records showed the driver had two prior DUI convictions.

Before answering more questions, the driver pulled out a bag from his right pocket and handed it to the officer saying, “”Marijuana … I thought you should know.”” According to reports, he then told the officer that the marijuana was not his, but rather belonged to one of the passengers, who asked him to hold it.

The passenger denied ownership.

The driver was arrested and booked at the Pima County Jail. The passenger accused of owning the marijuana was cited and released.
