A Victorian man has been arrested after he allegedly poured liquid from a jerry can throughout a car with three children inside.

Police say a small grey Mazda sedan pulled into a parking bay on Lloyd St, Moe, in Victoria's Gippsland region, at 1.30pm on Saturday.

It's alleged the man poured the liquid from a jerry can throughout the vehicle before he got out and started pouring the liquid on the roof.

The female driver of the car then drove off.

The 22-year-old Moe man attended a police station on Saturday night and is being questioned by police.
