A subpoena demanding the Twitter information of an account associated with the Occupy movement has caused outrage among activist and hacktivist groups online.

Allegedly demanding the Twitter information of Malcolm Harris' @destructuremal account, the subpoena appeared on Monday.

Listed as stemming from the State of New York's District Attorney's office, the subpoena demands Twitter present any email addresses associated with and all tweets from @destructuremal to a criminal court on 8 February, 2012.

The District Attorney's office has not responded to the International Business Times UK's requests for comment, though tweets from Harris indicate the subpoena is related to a disorderly conduct charge he is facing after being arrested at the Occupy Brooklyn Bridge march. "This is related to Brooklyn Bridge dis-con case as far as I know," read the tweet.

According to the document, if found guilty Harris could face up to a year in jail and a $1000 fine. @destructuremal went on to claim the request was part of a wider crackdown by the authorities on the Occupy movement. "How can they justify that scope? They clearly want to see what I was saying around Sept. 17th for unrelated reasons," read Harris' tweet.

Following Harris' public statements, Anonymous took an interest, tweeting messages of support and announcing the new OpSubpoenaThis campaign. "Subpoena on @destructuremal: tinyurl.com/8y9h3oe | #OpSubpoenaThis #CabinCr3w," read one tweet from YourAnonNews.

Though no direct threats were made, the collective did indicate it would be willing to mount some form of revenge attack. "@destructuremal ah yes, our policy is generally to go full-on raeg [rage] about it," stated the AnonyOps Twitter feed.

The incident in question occurred as the Occupy protest entered its third week in October, 2011 when Wall Street protesters attempted to march across the Brooklyn Bridge. While initially peaceful,devolved into clashes between protesters and the police after a number of the marchers ignored police warnings to use a pedestrian pathway.

The Occupy movement began in September 2011, following a blog post in Adbusters magazine. Inspired by the Arab Spring and Spain's Democracia real YA platform, Adbusters' called for all like-minded individuals unhappy with the current global political and economic system to march on Wall Street and mount an ongoing sit-in-protest.

The post quickly captured the imagination of several groups, leading to the #occupywallstreet hashtag trending on Twitter. The movement gained significant mainstream attention outside of Adbusters' native US base when the Anonymous collective took notice and publicly voiced its support.
