A Wake County sheriff's deputy was the subject of "a personnel action" after he used his office email account to send other deputies a free membership invitation for the National Rifle Association, officials said Friday

Deputy Brad Manville sent the message a day after the NRA unveiled a controversial ad criticizing President Barack Obama for his gun control proposals.

A spokeswoman for Wake County Sheriff Donnie Harrison said sending the message was an inappropriate use of county email. She said a "personnel action" was taken and the matter was closed. She did not provide further details.

Manville was one of five deputies who shot and killed a Cary man who took hostages during a 2011 bank robbery. He was also injured in the hand during an altercation with a suspect in a Wendell robbery in 2009.
