DALLAS, Texas (CNN) -- A police officer was killed Friday in a motorcycle accident as Sen. Hillary Clinton's motorcade made its way through downtown Dallas, the presidential candidate said.
The Dallas Police Department said a motorcycle officer was involved in an accident during Clinton's escort but did not immediately confirm the death.
The identity of the officer has not been released.
Clinton said she called the Dallas police chief and would contact the officer's family at an appropriate time.
CNN affiliate WFAA-TV in Dallas/Fort Worth reported the officer lost control of the motorcycle and struck a concrete abutment.
The officer was thrown about 30 to 40 feet, according to reports. No other vehicles appeared to be involved.
