AN ‘active aggressor’ has been reported at the Kentucky Exposition Center where thousands had gathered for a children’s sports game.

The venue in Louisville is also being used as a space for a fairground over the summer.

Just hours earlier, there was yet another incident involving gunfire at Blue Grass Airport, which culminated at the Richmond Road Baptist Church in Lexington on Sunday morning when a state trooper sustained a gunshot wound.

In a statement, Louisville Metro Police Department said there was an “active aggressor” at the Fairgrounds but that no victims have been found.

“Please avoid the area due to a heavy police presence,” they said.

Gunshots had previously been reported.

The area saw a large influx of people over the weekend due to the Run 4 the Roses Classic and the Nike Elite Youth Basketball League and Champions Youth Basketball League events.

Footage of the basket ball courts shared online showed people leaving the area as a siren rang out.

The LMPD confirmed  at 4:08pm Sunday that no shots have been fired and that there are no shooting victims.

Amid the panic, terrified families ran for cover.

Taking to social media, one witness said they were stuck in a bathroom with over 100 people.

“The park is on lockdown, my family and I are here and we’re locked down in a bathroom with maybe 150 people,” they wrote.

“Everyone is taking cover in buildings.”

An investigation is ongoing as responders continue to swarm the scene.

All basketball has finished for the day with officials not allowing reentry following the incident.

Cops have warned of huge traffic issues in the area but have made no comment about a suspect or any arrests.
