NEW YORK - Renowned media columnist at New York Times David Carr has died after suddenly collapsing in his office on Thursday night. He was 58.

Mr Carr was found and sent to Roosevelt Hospital, where he was pronounced dead.

Earlier in the day, he moderated a Times Talks discussion about the documentary Citizenfour, with its director Laura Poitras, journalist Glenn Greenwald and the film's subject, Edward Snowden. The film tells of Snowden's leak of National Security Agency documents.

Times Executive Editor Dean Bacquet paid tribute to Mr Carr in a statement, calling him the "finest media reporter of his generation".

"He was our biggest champion, and his unending passion for journalism and for truth will be missed by his family at The Times, by his readers around the world, and by people who love journalism," said Bacquet.
