( CNN ) Two deputies involved in the fatal attempt to arrest Eric Harris in Tulsa , Oklahoma , have been reassigned because of threats against them and their families , Sheriff Stanley Glanz said Monday in a news conference . The deputies were trying to arrest Harris when Reserve Deputy Robert Bates shot him . Unlike Bates , they are not charged with a crime , but have come under criticism for pinning Harris ' head to the ground as he said , `` I 'm losing my breath . '' Police appear on video saying , `` F*ck your breath , '' apparently in response . Sheriff Stanley Glanz did n't specify the nature of the threats , but said he was `` very concerned '' for their safety and that of their families . He did not say what the deputies had been assigned to do . Another sheriff 's official said the office has temporarily suspended operations of the agency 's drug unit pending the review of the April 2 shooting of Harris following a weapons sting . Glanz indicated he has not yet decided how to proceed with a review of their actions , saying any action may be delayed until after the court case involving Bates has been settled . Bates is charged with second-degree manslaughter in Harris ' death . Bates , who is free on $ 25,000 bond pending trial , shot Harris with his handgun after calling out , `` Taser , Taser , '' -- an indication he planned to use a stun gun to subdue Harris following a brief foot chase with the other deputies . Amid questions about his age -- 73 -- training and friendship with Glanz , Bates has said the shooting was accidental , and has apologized to the family . Lawyer releases training records for Tulsa deputy charged in killing . On Monday , Glanz also apologized to Harris ' family . `` We are sorry Eric was taken from you , '' he said . But he said his office holds itself to the highest national standards of policing , and said Monday that the FBI had cleared the agency of any civil rights violations in the shooting . Bates is white . Harris was black . There have been allegations , first reported by the Tulsa World newspaper , that some of Bates ' training records had been forged , or that he was unqualified to be serving on the force . The sheriff denied those allegations , saying he was certain Bates had qualified on the gun range and had extensive additional training . He said he was unaware of any forgery involving training records , and said he had not issued any training waivers for Bates , with whom he has been friends for more than two decades . But he said he supported prosecutor 's decision to proceed with the case . He also said he had brought in a Dallas police consultant who had previously examined the office 's policies and procedures for another look . Harris ' family has said the shooting reveals `` a deep-seated problem '' within the department and has demanded justice , and changes in policy .
Deputies reassigned after threats , sheriff says . The two deputies pinned Harris to the ground and one yelled `` F*ck your breath '' at him after he was shot .
