The NYPD is battling Twitter over the social media company's refusal to release the name of a user who threatened an attack "just like in Aurora."
The user claimed he would attack a Broadway theater where Mike Tyson's one-man show was playing on August 1, describing his plan in detail.
"This s**t ain't no joke yo I'm serious people are gonna die just like in aurora," the user tweeted, claiming he/she would use unlocked exit doors.
The NYPD plans to subpoena Twitter today for the user's identity.
The NYPD Intelligence Division used Twitter's system for emergencies to request the identity of the account holder, but was rebuffed, officials say.
"Twitter turned us down, so we dispatched police to cover the theater while we sought a subpoena to force Twitter to disclose the identity of the account holder," said NYPD spokesman Paul Browne in an emailed statement.
"We take the threat seriously, especially in light of the recent attacks in Wisconsin and Colorado," he said of the threat against the Longacre Theatre.
Alleged shooter Wade Michael Page killed six people Sunday at a Sikh temple in Oak Creek, Wis. Page, an Army veteran, was shot dead by police.
