Rescue workers are searching Brazil's Amazon Delta for a British
Greenpeace activist who went missing during a campaign against illegal logging in the area.
Radio technician Ms Emily Craddock (27), is believed to have fallen overboard from the Arctic Sunriseas it sailed from Porto de Moz on the Xingu River to the Para state capital Belem, 1,500 miles north of Rio de Janeiro.
The crew on the Greenpeace ship last saw her early on Friday. When they
discovered she was missing several hours later the boat turned around and retraced its course.
The environmental group said it was still hopeful of finding Ms Craddock.
"We don't know what happened yet, but at this moment, we don't state any
suspicion that her disappearance could have anything to do with the anti-logging campaign," a Greenpeace spokeswoman said.
A helicopter, Cessna plane and three inflatable boats were all searching the Para River for the missing woman.
Ms Craddock was one of several Britons on the boat, which has faced threats from loggers since late October when it began investigating illegal deforestation along the shores of the Xingu River, which flows into the Amazon River about 250 miles west of Belem.
