(26 May 2016) Four people were shot, and one person died Wednesday night at a Manhattan hip hop concert where rapper T.I. was getting ready to perform. Authorities say a dispute between two groups traveled from a top floor down to outside the green room at the Irving Plaza concert hall. It wasn't immediately clear what sparked the argument. Police say they've obtained video that shows part of the fatal shooting inside the concert venue. They say Thursday a man can be seen in surveillance footage firing off one round just outside a green room at Irving Plaza, in Manhattan's Union Square. Police say T.I. was in the venue at the time of the shooting but wasn't injured, and doesn't appear to be involved. They say about 1,000 people were there.
