Things got ugly outside Earth Nightclub in the Flats early Sunday morning around 4 a.m.
Police say 25-year-old Kevin Ghee was stabbed to death after arguing with a couple inside the bar.
33-year-old Clifton Robinson and 31-year-old Lydia Nord were arrested in Oberlin after police found their Chevy Tahoe, which witnesses saw at the scene of the crime.
The investigation is continuing, the Cleveland Police Department reported on Sunday, and no charges have been announced.
