On the evening of June 7, two boys were walking from Oak Street beach when they noticed that they were being followed by a group of about ten teenagers.

One of the boys from the group, allegedly 18-year-old Keith Alexander, walked up alongside the victims, at which point one of them asked Alexander if he could buy a cigarette from him. The boy took out his wallet to show that he had money and another boy from the group grabbed the wallet and fled south on Michigan Avenue.

The boys chased the offender and a physical altercation ensued in which the victims were knocked to the ground and hit in the face and abdomen by members of the group. Police tracked down and arrested Alexander, 18-year-old Marcus Clark and a 16-year-old male suspect.

A 28-year-old man told police that on the evening of June 11 he was approached by two men while locking up his bike on the 1500 block of N. North Park Avenue. The men told the victim that they had a gun and he gave them $200 in cash. The offenders then used their own lock to secure the man’s bike to a gate and ran away southbound.

A group of male suspects, estimated to each be between 15 and 25 years old, attacked a man and stole his iPod on a CTA train at the Chicago Red Line stop at around 4:30 p.m. on June 9.

The man, 35, told police that he had witnessed the offenders harassing people on the train when one of them approached him and asked what he was listening to before snatching the iPod from him. When the victim tried to retrieve the device, one of the offenders blocked his path and another punched him in the mouth with a closed fist.

On the afternoon of June 8, three boys were attacked by a group on a CTA Brown Line train. After boarding a train at the Irving Park stop, the victims told police that they were playing cards when a group of seven men and one woman began hitting and kicking them in the face.

During the attack, someone from the group took $150 from a wallet belonging to one of the victims. The offenders fled at the Chicago station.

Police arrested three young men for illegal possession of alcohol and disturbing the peace in the 800 block of North Michigan Avenue on the evening of June 11.

Officers spotted Joshua Bolden and Michael McCanny — both 19 years old — and another offender, a 17-year-old male, pushing each other and “play fighting,” in turn bumping into pedestrians and causing them to change course on the sidewalk. Bolden, a Southern Illinois University student, and McCanny, of the 7100 block of South Calumet Avenue, fled after being approached by the officers. The third offender was placed into custody and the other two were apprehended shortly after.

Officers reported that during a brief pursuit Bolden had run out in front of traffic, causing cars to swerve and stop abruptly. A search of the minor offender revealed that he was carrying a bottle of wine that he later admitted he had taken from a nearby grocery store.

A 62-year-old woman from Washington State had her car stolen after she handed over her keys to a man that she mistakenly took to be a valet.

The offender, believed to be between 25 and 35 years old, asked the woman for $10 to park her car, a 2010 Nissan sedan, before she entered a restaurant on the first block of West Illinois Street.

After learning that the valet was not on duty, the woman went back outside to find that her car was gone. The incident occurred on the afternoon of June 11.
