Shots rang out at a South Yarra pub before a nearby Chapel Street venue was set alight hours later, capping a chaotic night.

Two more bars attacked in Melbourne as fears grow

Drive-by shooting at South Yarra pub

A drive-by shooting, suspected firebombing, and a police shooting have unfolded across Melbourne in a chaotic night of violence.

Shots rang out outside the Emerson Hotel on Commercial Road in South Yarra in the early hours of Sunday, with police saying “several shots were fired towards the venue before the vehicle drove off.”

There were no reported injuries in the incident.

Just hours later and around the corner, a Chapel Street bar in Prahran was set alight.

Flames tore through the venue just before 5am, with police saying “a male offender set fire to the Chapel Street licensed premises before fleeing the scene on foot.”

A man suffered smoke inhalation after attempting to extinguish the flames, with police confirming “the building sustained significant damage as a result of the blaze.”

Earlier in the evening, officers responded to another volatile incident, firing a shot during a pursuit of a stolen car in Narre Warren South after 6pm.

Police said they “fired the shot when the officers left their car to walk towards the stolen vehicle and a second car allegedly drove towards them.”

Both vehicles fled the scene, and another was later abandoned. No arrests have been made.

In a separate incident, a 37-year-old man was arrested following an alleged violent attack on a tram in South Melbourne on Saturday night.

Police said a man and woman were approached by the offender behaving erratically near the intersection of St Kilda Road and Coventry Street shortly before 7pm.

The man was allegedly armed with a small steak knife and a hammer and “is said to have hit the victims a number of times.”

The pair, both aged in their 40s, were able to restrain the man until police arrived.

They were taken to hospital with minor injuries.

Police are continuing to investigate the incidents and are appealing for anyone with information to come forward.

At this stage, there is nothing to suggest the incidents are related.
