Charges were filed early Monday against five teenagers allegedly involved in separate robbery attacks Saturday night.
Police say the teens were part of a mob of between 15 and 20 men and boys connected to four attacks in Streeterville and along the lakefront.
Dvonte Sykes, 17, of the 7500 block of South Normal and two 16-year-old males were charged with felony counts of robbery and mob action after a man was knocked off his bike in the 700 block of North Lake Shore Drive, then punched and robbed. His cell phone and camera were stolen.
Trovolus Pickett, 17, of the 8400 block of South Dorchester, and Derodte M. Wright, 18, of the 3500 block of South State were charged in connection with an attack that happened earlier in the evening on Northwestern University’s Streeterville campus.
Police say the victim parked his scooter around 8:30 p.m. Saturday on the north side of Chicago Avenue across from Wieboldt Hall when up to 20 males approached him.
One of them threw a baseball at the victim's face and knocked him to the ground, according to an alert from the university. Several others from the group punched and hit him several times. The victim tried to protect himself and fought back.
The group eventually fled eastbound toward the lake. Chicago police and Northwestern University police responded, and police later arrested several members believed to be part of the group.
The victim was treated at the scene by Chicago Fire Department paramedics.
Nothing was stolen, and the victim could not provide descriptions of the multiple subjects involved, according to the alert.
Anyone who might have information that could aid this investigation is asked to contact Chicago Police.
