New York police chiefs are hunting down a user who threatened to massacre audience members at Mike Tyson's Broadway show.
The blogger tweeted about sick plans to embark on a killing spree similar to that of James Holmes, the suspect in the Aurora, Colorado murders, who stands accused of murdering 12 people and injuring 58 others during a midnight screening of the new Batman movie, The Dark Knight Rises, last month (20Jul12).
The Twitter user, whose identity is unknown, first posted on 29 July (12), "I might just shoot up this theater in new York I know they leave their exit doors unlocked. Ha now I gotta plan it step by step."
He went on to tweet, "i wanna kill alot (sic) of people" and added, "This s**t ain't no joke yo (sic) - I'm serious, people are gonna die like aurora".
Security has been stepped up at the Longacre Theatre, where former boxer Tyson is performing his one-man show, as cops put pressure on Twitter bosses to hand over information about the user's identity.
New York Police Department spokesman Paul Browne reveals executives at the social media website have been uncooperative so far and have denied detectives' requests for the user's contact information.
He tells the New York Post, "We'll cover the theatre until we find this guy. We needed a name and we needed it fast. Twitter (bosses) said no."
