Thomas Cowan, the owner of a South Buffalo bar, is to be arraigned Nov. 8 in City Court on a misdemeanor charge of assaulting Charles Flynn, a cousin of Erie County District Attorney John J. Flynn Jr.
The incident allegedly occurred in Doc Sullivan's, the Abbott Road bar Cowan owns, on St. Patrick's Day 2016.
A City Court official said Monday that Cowan has been charged with third-degree assault. Because the victim is related to the DA, the case was turned over to the Niagara County District Attorney's Office for prosecution, according to Joanna Pasceri, spokeswoman for Flynn.
Niagara County DA Caroline A. Wojtaszek confirmed her office is handling the case but declined to discuss details until after the arraignment.
Charles Flynn told The Buffalo News that he intervened after his son was punched near the door of Doc Sullivan's.
He said three men tackled him as he was leaving, inflicting a left knee injury that has required three surgeries, but the court official said no one but Cowan has been charged. Neither Cowan nor his attorney could be reached to comment Monday.
