Around 8:30 a.m. Sunday, a 53-year-old man was traveling on Lake Shore Drive when he was involved in a minor traffic crash. He pulled over in the 200 block of East Balbo Drive, and the people in the other vehicle involved in the crash approached him with a gun and announced a robbery, police said.

The unknown men fled in the victim’s vehicle with his personal belongings.

There were also two carjackings within minutes of each other Saturday night.

Just before 9 p.m. on LaSalle Street near Lake Street in the Loop, a white Toyota sedan bumped into an Audi Q-5. The driver got out, and then two armed people, possibly teenagers, stole the Audi at gunpoint.
