A former Indianapolis police officer faces up to five years in prison after pleading guilty to tipping off suspects in a federal drug investigation.
Federal prosecutors say 39-year-old Noble Duke pleaded guilty Friday to disclosing wiretaps to damage a criminal investigation.
Duke resigned last month. He had been part of a federal drug task force from 2005 to 2007.
Federal agents monitored cell phone conversations between members of several suspected cocaine-dealing groups as part of the probe. Officials say Duke told some of the suspects that their calls were being monitored, that an indictment was pending and that police planned to arrest people on a certain date.
Duke could not be reached for comment.
