A boat crashed into a ferry and then fled the scene, leaving one person dead and several more injured, Florida’s Clearwater Police Department said.

It was declared a “mass casualty incident” by the Clearwater Fire & Rescue Department due to the number of injuries.

Police said all injuries were aboard the Clearwater Ferry, which “came to rest on a sandbar just south of the Memorial Causeway bridge.”

“All patients and passengers have been removed from the boat,” police said on X. “All local hospitals have been notified. Multiple trauma alerts have been called with helicopters transporting two of the more seriously injured.”

Police believe they have found the other boat involved in the crash, FOX13 reported.

A police official told the outlet that at least six people were injured and two of the victims need to be flown to the hospital for urgent treatment.

Videos on social media showed several first responders rushing to the scene with lights flashing. Police cautioned drivers to avoid Memorial Causeway.

The U.S. Coast Guard and Florida Fish & Wildlife Conservation Commission will investigate the crash.
