MESA, Ariz. (AP) -- A retired Mesa police sergeant has been arrested on suspicion of sexual exploitation of minor.
Mesa police say 66-year-old Russell Dean Millsaps was taken into custody Thursday afternoon after a search warrant was served at his home.
They say the arrest was part of an interstate federal child-pornography investigation.
Details of the case against Millsaps weren't immediately released.
Authorities say Millsaps was a longtime patrol sergeant who retired from the Mesa Police Department in 1995 after working for more than 25 years as an officer.
Police didn't immediately know Thursday night if Millsaps had an attorney yet.
