Two Spalding County firefighters, one of them a battalion chief, have been indicted by a federal grand jury on charges that they have been tipping off drug traffickers to police activity in and around Griffin, the U.S. attorney for the Northern District of Georgia announced Monday.

Spalding Battalion Chief Dwayne Tyrone Coggins, 47, and firefighter Michael Owens, 37, were arraigned Monday after the grand jury indicted them last week.
