Ivan Watson, a correspondent for CNN reporting from Istanbul, Turkey, was delivering a report on the heavy police presence on the one-year anniversary of the Taksim Square protests, when he was taken in by authorities on live TV.

Police can be seen demanding Watson's passport and asking over and over if he's a journalist. The footage then cuts out.

Watson and the CNN team were released a half an hour later, as he told Twitter.
