CHICAGO (WLS) — The details of these two assaults are concerning, especially given the fact that, in a few days, thousands more people will flock to Chicago for festivals like Lollapalooza, where countless attendees will rely on rideshares to get them safely home.

Chicago police said so far, they have heard of two incidents within the past few months with similar circumstances.

In each incident, a man posing as a rideshare driver picked up female victims and later sexually assaulted them.

Police say the man drove a mid-sized black SUV, which was not the vehicle ordered by either victims on their rideshare apps.

The most recent incident happened along a busy stretch of North Wells Street near North Avenue in the Old Town neighborhood on July 19 just after 2 a.m.

The first reported case happened back on March 30 at about 5 a.m. along a residential area on North Lake Shore Drive near Cedar Street in the Gold Coast neighborhood.

Police say these incidents are good reminders for rideshare passengers to verify the license place and make and model of the vehicle they ordered.

It is also good idea to share that ride share information or location with either family or friends.

The suspect is described as a man between 35 to 45 years old with a heavy build.
