The straphanger stabbed to death on a Brooklyn train was an ex-con who’d been harassing a couple on board – and punched the woman before her boyfriend knifed him in the chest, police sources said Wednesday.
Devictor Ouedraogo, 36, was hassling other commuters on board a northbound J train approaching Marcy Avenue in Williamsburg Tuesday evening when he started arguing with Jordan Williams, 20, and his gal pal, the sources said.
During the clash, Ouedraogo, of Bedford-Stuyvesant, socked the woman in the face, the sources said.
Williams, of Hollis, Queens, then knifed the alleged aggressor in the chest, according to the sources.
The wounded man stumbled out of the train and onto the platform, the sources said.
Officers responded to a 911 call about the stabbing just after 8 p.m., cops said.
EMS also responded and rushed Ouedraogo to Brooklyn Methodist Hospital, where he was pronounced dead.
The couple stayed on the train, but were tracked down by police at the Chauncey Street station, the sources said.
Williams was charged late Wednesday morning with manslaughter and criminal possession of a weapon, authorities said. The woman, whose age was not released, was initially also in custody as a “person of interest,” but was later released, cops said.
Police have said the couple did not know Ouedraogo prior to the fatal clash.
Ouedraogo did time in state prison in August 2009 for an attempted robbery in Queens, records show.
He was sentenced to three and a half years and was paroled in April of 2012 to immigration.
