Melbourne's Metropolitan Fire Brigade said students and staff were asked to leave the building “as a precaution” while firefighters investigated. However, nothing except an extremely smelly fruit was found. “After a comprehensive search, firefighters identified the smell was not chemical gas, but gas generated from a rotting durian, an extremely pungent fruit which had been left rotting in a cupboard,” the fire service said in a statement.
According to independent.co.uk, it turned out that the famously strong smell of the durian had made its way through the building via the air conditioning system. The fruit, which does not need to be rotten to offend with its odour, is commonly banned across hotels and public transport across southeast Asia.
“The Environment Protection Authority will oversee the removal and storage of the waste,” the firefighters’ statement added. They have since given the university the all clear.
