Chicago Fire is taking a brief hiatus.

The NBC drama stopped filming immediately after gunfire was exchanged close to the set, Variety first reported.

The Chicago Police Department confirmed to PEOPLE that a gunman fired shots around 1:45 p.m on Wednesday near the 5900 block of W. Madison St. in Oak Park, Ill. The suspect then fled the scene in a black SUV. No one was struck by the gunfire.

The incident is currently under investigation, and no one is in custody.

The Chicago Fire set promptly entered into security protocol on Wednesday and halted production after shots were heard. According to a source close to the series, no one connected to the production was involved or injured.

Filming will resume Thursday.

There were a few surprise guests at Kelly and Stella's wedding from Chicago Fire past. But the biggest was Matt Casey (Jesse Spencer), who served as Kelly's best man.

"Jesse Spencer so understands the character — and especially the relationship that Casey has with Severide, the bond of that friendship — and he knew the character had promised to be there at the wedding as the Best Man," Chicago Fire co-showrunner Andrea Newman told PEOPLE of the decision to bring Spencer back.
