Chicago shooting suspect arrested on tourism boat after off-duty Cook County sheriff's deputy wounded him

CHICAGO - Another shooting in downtown Chicago Friday night turned into a chaotic scene on the Riverwalk.

A man was wounded during a shootout with an off-duty Cook County sheriff’s officer near Millennium Park.

The 22-year-old was trying to enter the park about 7:20 p.m. in the first block of East Monroe Street but refused to be checked by a metal-detecting wand at the entry point, Chicago police said.

The man then jumped a fence to gain entry and as security approached, he pulled out his gun and fired, police said. An off-duty Cook County sheriff’s officer, working as a security guard, returned fire.

The man was shot and fled on foot. He was caught and taken into custody in the 300 block of East Riverwalk, police said, then taken to a nearby hospital. His injuries were not considered to be life-threatening.

A witness says the man ran onto a tourism boat and tried to jump into the Chicago River.

"He was trying to jump off the boat," she said. "I don't know from where he got shot but he had blood on his back."

Amateur video shows the suspect was taken from the scene on a gurney.

Charges were pending, according to police.

An investigation is ongoing.
