MEXICO CITY – A Mexican official said Friday that Canadian pop star Justin Bieber and his entourage were asked to leave the Mayan archaeological site of Tulum after he apparently tried to climb onto or among the ruins.

The official of the National Institute of Anthropology and History spoke on condition of anonymity because he or she was not authorized to be quoted by name.

Bieber was visiting the seaside ruins on Thursday when the incident occurred.

The official could not specify which of the site’s structures Bieber allegedly had climbed, but said he was “asked to leave.”

Visitors can climb some pre-Hispanic pyramids in Mexico, but officials rope off or place ‘no entry’ signs on some ruins that are considered vulnerable or unstable.

Bieber has apparently been on vacation in the Tulum area, on Mexico’s Caribbean coast south of Cancun, for several days.
