ST. LOUIS COUNTY, Mo. – Police are investigating an exchange of gunfire Tuesday morning along Interstate 44 in St. Louis County.

St. Louis County Police say two people reportedly exchanged gunfire in the eastbound lanes of I-44 in St. Louis County near Bowles Avenue. It happened during the 8 a.m. hour.

One person was taken in custody in connection with the case, but the St. Louis County Prosecuting Attorney’s Office has refused all charges as of Tuesday afternoon.

Investigators say two drivers pulled over along I-44 at some point, which was then followed by an exchange of gunfire.

One man was shot in the hand and ended up in the hospital with a non-life-threatening injury. The driver of one of the car linked to the shooting then headed toward I-270 and Gravois Avenue, where he reportedly called police about the incident.

No one else was struck by gunfire, though the situation led to some traffic delays Tuesday morning.

The Missouri State Highway Patrol and county police are both investigating various circumstances around the incident.

This is a developing story. FOX 2 will update as more information becomes available.

CORRECTIONS: The St. Louis County Police Department initially told FOX 2 of two pieces of information Tuesday morning that have since changed.

And we were told one of the drivers was struck in the hand, which county police have not confirmed at this point. The story has been reflected to include confirmed details as of 5 p.m. Tuesday.
