LITTLE ROCK — Charges will not be pursued against an Arkansas state legislator who was arrested Monday after he filmed a police traffic stop in Little Rock, authorities said Tuesday.

Little Rock police arrested Rep. John Walker, D-Little Rock, and took him to the Pulaski County jail, where he was booked Monday afternoon on suspicion of obstructing governmental operations and released about two hours later.

A police report states that police stopped a vehicle for having no license plate and arrested the driver, who had no driver’s license and was wanted on warrants. Walker began filming and walked into the area of the traffic stop, and when told to leave the area he said, “Arrest me,” according to the report.

Pulaski County Chief Deputy Prosecutor John Johnson said Tuesday the prosecuting attorney’s office was not involved in the decision by the Little Rock Police Department not to charge Walker.

“That was their decision,” he said.

A police department spokesman did not immediately return a call Tuesday seeking comment.

Walker has served in the Arkansas House since 2011. He was a co-sponsor of a state law passed last year that allows members of the public to observe and record events that happen in public places where they are lawfully present.
