CHICAGO — An 18-year-old is now facing five attempted murder charges after prosecutors say he drove into a line of Chicago police officers during a chaotic early morning crowd dispersal on the city’s Near West Side.

Authorities identified the suspect as Rashad Johnson. Chicago police said he was arrested around 3:23 a.m. Sunday near Roosevelt Road and South Loomis Street, where officers had been responding to a large crowd near the Brooks Homes area.

The gathering was first described as a “teen takeover,” but Alderman Jason Ervin later said it appeared to be an after-prom gathering that got out of control. Police were trying to clear the area when the situation turned violent.

According to prosecutors, Johnson was driving a Ford Fusion with two other people inside. As he approached officers blocking Roosevelt Road, a marked squad car with lights and sirens activated attempted to stop him.

Prosecutors said Johnson was driving westbound in the eastbound lane. He allegedly slowed the vehicle almost to a stop, but instead of stopping, he accelerated and turned south onto Loomis Street.

As the car turned, prosecutors say it went onto the curb and struck the first officer. Johnson then allegedly continued accelerating down Loomis Street in the wrong lane, hitting four more officers before crashing into a parked police vehicle and a utility pole.

All five officers were taken to local hospitals. Prosecutors said their injuries included cuts, severe bruising, and concussions. They were later treated and released.

Johnson was taken from the driver’s seat and placed into custody. Prosecutors said officers found a loaded MAC-10 style semiautomatic handgun with an extended magazine on his waistband. Authorities also said he did not have a valid FOID card.

Johnson is now charged with five counts of attempted first-degree murder, five counts of aggravated battery with a deadly weapon, aggravated unlawful possession of a weapon, aggravated unlawful possession of a loaded weapon without a FOID card, and criminal damage to government property.

In court, prosecutors argued that Johnson intentionally drove into the officers. His defense asked for him to be released on electronic monitoring, saying he had no criminal background and arguing that he did not strike the officers on purpose.

The judge denied pretrial release and ordered Johnson detained while the case moves forward.

Police also said a 19-year-old man was shot about 30 minutes later in the nearby 1100 block of West Roosevelt Road, but investigators have not said whether that shooting was connected to the large gathering.

The case remains under investigation.
