A photographer taking pictures of a BP refinery in Texas was detained by a BP security official, local police and a man who said he was from the Department of Homeland Security, according to ProPublica, a non-profit news organization in the U.S.

The photographer, Lance Rosenfield, said he was confronted by the officials shortly after arriving in Texas City, Texas, to work on a story that is part of an ongoing collaboration between PBS and ProPublica.
