An Italian cafe in Warwick was shut down overnight and its co-owners arrested after allegedly operating the venue without enforcing vaccine mandates.

Topolinis Caffe proprietor Jodie Jardine and her daughter were taken by police around 6pm on Monday, before they were dropped back to the restaurant in the early hours of the morning, to huge applause from onlookers, some of them anti-vaxxers.

Jodie’s husband Phil Jardine told 6PR Breakfast his café did not believe in forcing people to show their medical records, and vowed to reopen the business on Tuesday night.

He expected a stronger presence of supporters tonight at the business, which they have run since 1998 and employs 20 people, most of them unvaccinated.

WA Police said they initially closed the café earlier that day after a public complaint one of the staff were unvaccinated.

“About 5:30pm, police re-attended and found the café open and trading for business,” a police spokesperson said.

Under WA’s COVID mandates, proof-of-vaccination has been required to enter hospitality venues since January 31. To date, more than 98 per cent of the population over 12 has received at least one dose.
