CLAYTON, Mo. (AP) — The acting head of St. Louis County police has issued an order saying that all officers must follow a county mandate to either get the COVID-19 vaccine or submit to weekly testing.

The order was issued even though an officer has filed a lawsuit challenging whether the county’s mandate should apply to the police department, which is primarily government by its chief and the St. Louis County Board of Police Commissioners.

A planned Friday hearing on the officer’s lawsuit was cancelled after the order.

Lindeman’s attorney, Christopher Graville, said he is weighing how to proceed with Lindeman’s lawsuit after the order.
