High temperatures during the Fourth of July celebration in Catonsville resulted in several people succumbing to heat-related issues.
Baltimore County police spokeswoman Julia Hardgrove said she did not have the exact number of how many people required medical attention during Wednesday's 66th annual parade and other festivities.
The volume of calls for medical attention prompted Baltimore County to send extra medic units to the area, however, Hardgrove said Thursday morning.
At least one person was taken to Saint Agnes Hospital, Hardgrove said.
Forty minutes into the parade, a man who appeared to be unconscious was taken to the Catonsville Fire Department.
At 3:40 p.m., several people loaded the man into the back of the truck of Baltimore's Marching Ravens at the 800 block of Frederick Road.
He was taken about a block to the Catonsville Fire Department on Frederick Road near Egges Lane, where he was taken away in an ambulance.
