He said the contractors had provided a “fantastic” service to students for many years.
”It is disappointing that individuals choose to target community organisations like schools. At the end of the day, we are trying to create a safe and comfortable environment for our staff and students,” he said.
”Situations like this leave everyone unsettled. It’s an unfortunate way to start the new term.”
Wilton said police were investigating the incident and looking at security footage.
He said it would be some time before the contractors would have the canteen fully up and running again, but they hoped to offer some limited services to students during the next few days.
