Simos Kandias, owner of Briki cafe in Thornbury, received a call in the early hours of Monday morning to news the windows and doors of his cafe had been shattered.
“I was informed at 4am by my delivery guys my windows had been smashed,” he told Sky News Australia.
Mr Kandias then found a note stuck to his door which wrote: “Do what Daniel Andrews says and we will burn your shop down and kill you motherf**kers”.
“I don’t feel safe, not fully, no,” he told Sky News Australia.
“That’s why I’m looking at taking other measures, upgrading my security and possibly installing shutters.”
Photos posted on social media show the main window and door had been smashed with a brick, and a death threat had been taped on top of his COVID safe check-in displays.
A photo taken from inside the cafe displayed shattered glass spilling on the bench and a knife on the ground.
Mr Kandias posted the news to a local Facebook group, urging fellow business owners to upgrade their security if they have the means to.
“Hey guys, you might have heard about the damage at our cafe this morning. Really sad and uncalled for,” it wrote.
“I’m just trying to operate in a COVID-safe manner. I’m really disappointed and sad but we will be ok.
“To the fellow business owners, please upgrade your security if you can and protect yourselves as much as possible. Thank you for your amazing support. Stay safe people.”
Victoria Police say investigations are “ongoing” following the incident overnight on Sunday.
“Police are investigating a report that a brick was thrown through a café window in Thornbury overnight and a threatening note left,” a spokesperson said.
“The investigation is ongoing.”
Locals have taken to Facebook to voice their support with Ged Kearney, MP for Cooper in Victoria condemning the act on Facebook last night.
“One of our favourite local cafes was brutally attacked by anti-vaxxers last night,” she wrote.
“They smashed windows and left notes threatening to burn the shop and kill those who work there.
“This is not okay. Whatever your opinions may be on mandatory vaccinations, everyone should feel safe at work.
“I’m looking forward to returning to Briki Cafe. With the community’s help and support, I know they’ll bounce back in no time.”
