Richmond voters on Tuesday re-elected the city’s top prosecutor to a fourth, four-year term.

Richmond Commonwealth’s Attorney Michael N. Herring, who was first elected in 2005, ran unopposed in Tuesday’s contest.

Correct vote totals were unavailable Wednesday evening on the state Department of Elections website.

The commonwealth’s attorney’s office chiefly prosecutes violations of state law and local ordinances in district and circuit courts.

Mr. Herring earns roughly $137,000 a year. The Richmond native often has been mentioned as a potential contender for other offices, including mayor.
