Police in China said they rescued two men trapped in a burial chamber for 25 hours, then arrested them as suspected grave-robbers.
The men and three others were allegedly attempting to excavate a tomb from the Tang Dynasty (between 618 and 907), in Fuping County, Xinhua reported Monday.
Two of the men became trapped in the chamber Saturday.
Three rescuers with oxygen masks rescued the two men after more than an hour of searching for them, said Sun Weidong, the officer in charge of the rescue operation. The men were pulled out through a crack in the top of the chamber.
