SWARTZ CREEK, Mich. (AP) — About five people picketing in the United Auto Workers strike outside a Flint-area General Motors plant suffered minor injuries Tuesday when a vehicle leaving the plant struck them, police said.

The striking workers were blocking a driveway, and an employee was trying to leave the Flint Processing Center in Swartz Creek when the collision occurred just before 4 p.m., Chief Matthew Bade of the Metro Police Authority of Genesee County said.

The employee drove through the picket line to leave the plant, Bade said. The employee has not been located.

GM spokesperson Jack Crawley issued a statement saying the company “is committed to the health and safety of all employees.”

UAW Region 1-D President Steve Dawes told The Flint Journal that two of the five people struck were taken to a local hospital.
