A West Texas doctor has been arrested on charges of misusing official information to retaliate against nurses who reported him to the state medical board.

Winkler County's chief deputy sheriff says Dr. Rolando Arafiles Jr. has been freed on his own recognizance. Arafiles' phone number was not accepting calls Wednesday.

Arafiles levied the same charge against two nurses at Winkler County Hospital in Kermit after an unsigned letter was sent to state medical regulators in 2009. It outlined concerns including Arafiles' alleged attempt to use hospital supplies for at-home procedures.

Both nurses were charged after Arafiles asked the sheriff, a friend, to investigate who sent the letter.

In an arrest affidavit, investigators say Arafiles believed the charges would thwart the board's investigation.

Charges against one nurse were dropped. The other was acquitted.
