( CNN ) -- Five law enforcement officers were among 70 people in Arkansas charged in a federal drug-trafficking crackdown that also involved public corruption charges , authorities said Tuesday . The five officers took bribes to look the other way while crimes were being committed , authorities said . Investigators are continuing to look at other law agencies for criminal misconduct , authorities said . On Tuesday , 800 federal and local authorities arrested 51 of the 70 people , officials said . Five others were already in custody , and the remaining 14 defendants are considered fugitives , authorities said . The Arkansas National Guard was also involved in making the arrests , authorities said . One agent was shot while serving warrants , and he is hospitalized with injuries that are not life-threatening , authorities said . The law enforcement figures named in indictments are Helena-West Helena Police Department officer Herman Eaton , 46 ; Helena-West Helena officer Robert `` Bam Bam '' Rogers , 35 ; Helena-West Helena Sgt . Marlene Kalb , 48 ; Marvell police officer Robert Wahls , 42 ; and former Phllips County Deputy Sheriff Winston Dean Jackson , 44 , who 's now a Helena-West Helena police officer , according to court records and a prosecutors ' statement . Their attorneys could n't be immediately determined or reached for comment . A two-year investigation , called Operation Delta Blues , focused on public corruption , cocaine and crack cocaine trafficking , and money laundering in the Helena-West Helena and Marianna , Arkansas , areas , authorities said . Investigators used 16 court-authorized wiretaps in their investigation , officials said . `` Today 's indictments and arrests are merely the beginning . We believe there are more cases of corruption , and we intend to press forward with our investigation to weed out those who would sacrifice their oath and violate the public 's trust , '' said Valerie Parlave , special agent in charge of the Little Rock field office for the Federal Bureau of Investigation . `` Several of those indicted today are no strangers to law enforcement . Many have been charged in state court with some of the serious class ( of ) felonies , including murder , '' Parlave continued . `` Yet they remain free today . As our investigation moves forward , we continue to find instances where these violent felonies were never completely prosecuted and some of the most serious charges were dropped . '' Added U.S. Attorney Christopher R. Thyer of the Eastern District of Arkansas , `` Our commitment to eradicating drug trafficking and violent crime has never been stronger . `` When these two elements are mixed with law enforcement corruption , it can make for the perfect storm in a community . It can paralyze honest law enforcement action , silence witnesses , and erode public confidence in our system of justice , '' Thyer said in a written statement .
