Twitter has been forced to reveal information about the source of a tweet saying people were going to die at the Broadway theatre staging a one-man show by former heavyweight champion Mike Tyson.
The New York Police Department issued a subpoena after Twitter refused to cooperate in an investigation into posts that referenced the fatal shooting of 12 people last month at a showing of The Dark Knight Rises at a Colorado cinema.
Police said the tweets appeared to be aimed at the audience for Mike Tyson: Undisputed Truth - the solo show directed by Spike Lee at the Longacre Theatre in Manhattan.
"This s**t ain't no joke yo I'm serious people are gonna die just like in aurora," police said one tweet read.
Another from the same account warned: "I'm in Florida rite now, but it'll happen i promise I'm just finishing up my hit list."
Before complying with the subpoena, Twitter had told the NYPD in an email: "We appreciate the timeliness and sensitivity of this matter, and have reviewed the reported Twitter account.
"While we do invoke emergency disclosure procedures when it appears that a threat is present, specific and immediate, this does not appear to fall under those strict parameter as per our policies."
A police spokesman said security had been stepped up at Longacre as a precaution.
