Four were transported to a Wichita medical facility with  injuries Sunday afternoon following a two-vehicle collision in Butler County.

The wreck occurred at about 3:45 p.m. on U.S. 54 near Indianola Road when an eastbound Toyota Camry lost control and veered across the median into westbound traffic, striking a Toyota minivan.

Four injuries were reported by the Butler County Sheriff's Department — two passengers from the Camry and two juvenile passengers from the minivan. All were transported in serious condition. Four other passengers in the minivan were treated at the scene and did not need medical transport.

"The car made some avoidance maneuvers," Tony Wilhite, Butler County undersheriff, said on scene. "They believed they were going to be in an accident westbound. They lost control of their vehicle, entered the median and crossed over."

Passengers in the Camry were from Wichita. Passengers in the minivan were from Augusta, Wilhite said.

The eastbound lanes of U.S. 54 were closed down and traffic was diverted onto Meadowlark Road.

Butler County Sheriff, Andover Fire Department, Police Department and Emergency Medical Services, Kansas Highway Patrol and members of the Kansas Army National Guard were on scene.
