Mexican police arrest loggers over Greenpeace murder

MEXICO CITY -- Mexican police have arrested two lumberjacks accused of murdering an anti-logging activist, authorities said on Thursday, following criticism from environmental group Greenpeace of official foot-dragging.

A spokesman at the state attorney general's office said police arrested the two men, who are brothers, on Wednesday. Authorities are searching for two other men in connection with the May 15 killing.

Prosecutors called the detention proof the government is tackling illegal logging.
