An investigation is underway after vandals damaged six vans used by the Bluegrass Chapter of the American Red Cross.
The buses are used to transport people to and from doctor appointments each day.
Earlier this week, drivers at the Red Cross discovered the fuel lines on six vans had been cut, outside the Red Cross office on Newtown Pike in Lexington.
Gas was also siphoned from the tanks.
Officials say the damage to the buses meant endangering the lives of people who rely on the transportation the Red Cross provides.
"The vast majority of the people who use the rides really need it for medical emergencies, so for someone to steal a few gallons of gas, they really put others lives in danger," Winn Stephens of the American Red Cross said.
Officials say maintenance crews were able to have the buses repaired the same day the damage was discovered.
The vans are a service of LexTran, and are not funded through donations.
