Federal prosecutors failed three times to persuade a grand jury to indict a woman accused of assaulting an FBI agent during an immigration operation in Washington, D.C.

Three different federal grand juries declined to indict Sydney Reid for assaulting, resisting, or impeding officers, prosecutors disclosed in a court filing late on Monday. Prosecutors then downgraded the offense to a misdemeanor.

U.S. prosecutors in Washington sought to bring a felony assault charge against Reid, accusing her of pushing the FBI agent’s hand against a cement wall. The July 22 confrontation happened as Reid was filming officers who were transferring two men accused of gang activity into federal immigration custody outside a Washington jail, according to court documents.

The alleged assault occurred while Reid was being pinned against the wall by federal agents. Officers sought to subdue her after she attempted to get between law enforcement and one of the suspects, according to a charging document.
