KENOSHA, Wis. (AP) — A man accused of assaulting a police officer during the protests in Kenosha over the shooting of Jacob Blake has been indicted on two federal counts.

Authorities announced Wednesday that 27-year-old Ashton Howard, of Kenosha, is charged with obstructing a law enforcement officer during a civil disorder and unlawful transport of firearms as a convicted felon.

He faces a maximum penalty of 15 years in prison on the two charges.

Prosecutors say a Kenosha police officer was helping to remove a damaged police vehicle on Aug. 23 when Howard threw a heavy object at the officer and knocked him unconscious.
