A BIZARRE war on hipsters has begun as many alternative bars and cafes become targets for senseless attacks.

Alternative hangouts in Melbourne’s gentrified suburbs have been trashed and one had windows smashed and “hipster scum” graffitied on the walls.

One bar in Fitzroy, 2km from Melbourne’s CBD, even received a bomb threat on New Year’s Day.

It turned out it was all a hoax, but the Bimbo Deluxe pub had to evacuate patrons about 11.30pm.

The Herald Sun reports the bar is now taking legal action against the drunk patron who thought it would be a good joke, but instead the gag lost the bar a significant amount of business.

Also on New Year’s Day, about 5am, 8-Bit burger in Footscray, 5km from Melbourne’s CBD, had its front window smashed and was branded with the words “f*** off hipster scum”.

Owner Shayne McCallum said this was almost the fourth attack on the business and there had also been some break-ins.

Mr McCallum was tagged in a photo on Instagram of a car parked outside the store and noticed the graffiti.

He told 3AW it was funny at first, as he’s about as far as you can get from a hipster.

But the joke turned sour when he noticed the 14 broken window panels on his restaurant.

Mr McCallum said there was CCTV which he would go through in an attempt to find the culprit.

A hipster cafe in East London, Cereal Killers, has also been the victim of attacks from angry mobs in the past.

In September 2015, the cafe was splattered with paint and “scum” was written across the front window. It is believed the cafe was trashed by a mob of anti-gentrification protesters.

Littlefoot Bar in Melbourne has also fallen victim to hipster attacks since opening about two years ago.

Fairfax Media reports the front of the bar was slapped with anti-gentrification signs and said the owners were “profit-seeking hipsters”.

Human geography lecturer Oli Mould, from Royal Holloway University, wrote on The Conversation some people feared gentrification, leading them to take it out on hipsters.

He said once affordable suburbs were being revamped into hipster paradises, causing prices to soar and homelessness was hitting record levels.

He said “even middle-class people have a right to be angry at an urban capitalism that is pricing them, and their children, out of the city”.

“Faced with the acceleration of the gentrification process, and despite the explosion of anti-gentrification campaigns, the protesters’ feelings of helplessness is understandable, and the desire to respond angrily inevitable,” he said.
