The Chinese side of Everest in Tibet was described as out of control after one Canadian had all his gear stolen and was abandoned by his Sherpa. Another sherpa helped the victim get off the mountain safely and gave him some spare gear. Other climbers have also reported missing oxygen bottles, which can be worth hundreds of dollars each. Hundreds of climbers pass by people's tents, making it hard to safeguard against theft.. In the late 2010s, the reports of theft of oxygen bottles from camps became more common.
