Young prankster sprays milk on women cruising Yarra River

A group of women enjoying a picnic boat cruise down the Yarra River had their day spoiled when a pest pegged milk on them from a bridge above.

A sunny birthday celebration along Melbourne’s Yarra River over the weekend has been soured by milk at the hands of a young prankster.

A young Victorian man boasted online on Sunday of several incidents in which milk was poured on members of the public around the Yarra in Southbank.

Some show a young man hurling milk off the Evan Walker Bridge in Southbank onto people in hired leisure boats below.

One of the unfortunate parties was a group of friends who hired a Go Boat for a birthday celebration.

Footage from both the party and the alleged offender shows the moment they were covered in milk.

“You guys want some milk,” the young prankster asks.

“Don’t! Oi!” the four young women plead before they, their cheese platter and Bluetooth speaker are soaked by dairy.

The aftermath shows the women and their belongings drenched.

According to the women their Go Boat trip was credited for another day.

Other videos gloating about the pranks show other hired boat customers copping the same treatment with the milk as others appear to be egged.

A Victoria Police spokesperson told news.com.au that none of the incidents were reported to the police.
