LAFAYETTE - A part of downtown Lafayette was placed on lockdown Wednesday morning after witnesses spotted what appeared to be a person with a gun atop a building.

KATC reports the situation began after police received reports of a person armed with a gun in a parking garage. A SWAT team and drones were called to check the roughly two-block area, which has since been cleared by police and sheriff's deputies. 

Field trips from two different schools were reportedly visiting a nearby children's museum at the time of the lockdown. 

No injuries have been reported.
