A teenager was rushed to the hospital in critical condition after he went missing while swimming and firefighters rescued him from Lake Michigan in Waukegan Monday evening.

The Waukegan Fire Department and Waukegan Police Department responded around 5:30 p.m. Monday to the Waukegan North Harbor, 199 East Madison Street in Waukegan, for a report of a water rescue.

Waukegan Fire Department Battalion Chief Todd Zupec said 911 dispatchers reported that a subject was under the water in the harbor channel area.

Bystanders reported that a person went missing in Lake Michigan and fire crews began a search effort.

Emergency crews arrived at the Waukegan Harbor and at the Waukegan Municipal Beach.

Zupec said friends of the victim were located and reported they had been swimming in the channel and one of their friends did not make it out of the water. The friends then called 911 for help.

The Mutual Aid Box Alarm System (MABAS) was activated to the box alarm level, prompting the response of boats, divers and sonar equipment from fire departments throughout the county but was canceled a short time later.

The U.S. Coast Guard also responded to aid in the search.

Bill Barron, who said he had been in the area of the Waukegan Harbor for most of the day, heard ambulances, fire trucks and police cars responding to the area.

The fire department launched a boat to the south rocks and returned to the dock just after 6:20 p.m., Barron said.

Zupec said divers were deployed and were able to find the teenage male victim within minutes of searching along the breakwall near the bottom.
