A Mexican official says 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 the ruins.<br />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.<br />Bieber was visiting the seaside ruins on Thursday when the incident occurred.<br />The official could not specify which of the site's structures Bieber allegedly had climbed, but said he was "asked to leave."<br />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.<br />Bieber has been involved in several incidents in Latin America in recent years.
