Paramedics transported 28 people in their teens and early twenties to all six area hospitals as a precaution.

“The bus in front of us stopped really quickly and our driver didn’t have time to break, so we hit the back of them,” one of the girls told KDKA’s Kym Gable.

“We instituted a mass casualty incident, which brought in several additional ambulances from outside the city for a total of nine medic units that helped us during this event,” Pittsburgh Public Safety Director Wendell Hissrich said.

Pam Surano’s Report:

There were a total of 3 buses carrying ballet students from a Summer Intensive Program at Chatham University. They were on their way to the Gateway Clipper for a field trip after training.

Samantha Condo was not one of the girls transported.

“About half of us from this bus were taken outside onto an ambulance for different reasons, so we’re about 50 percent of the original people from this bus,” Condo told Kym Gable at the scene.

Another girl added, “The [people on the] back of the first bus got pretty hurt.”
