Authorities in Chiang Mai, a city in northern Thailand, are investigating the deaths of dozens of tigers at a popular tourist attraction this month, BBC reported. 

Seventy-two tigers died in the span of less than two weeks across two facilities of Tiger Kingdom Chiang Mai, a park where visitors can touch and interact with tigers.

The local livestock department said samples from the tigers showed canine distemper virus - though authorities have not confirmed how the outbreak happened, according to BBC.
