A 35-year-old Roxbury man was waiting outside the 7-Eleven convenience store, near many popular bars, in Cambridge’s Central Square early Saturday morning when he was stabbed, according to a joint release from the Middlesex District Attorney’s Office and Cambridge Police Department.

Tywann Jones died at Mass. General Hospital in Boston three hours later, at about 4:40 a.m., authorities said. No one has been arrested in connection with his death, and the investigation is ongoing, according to the release.

The stabbing occurred outside the 7-Eleven, which is on Mass. Ave., about a block from the MBTA’s Central Square stop on the Red Line.
