Mass chaos erupted in Melbourne’s Chapel Street on Saturday after a man wielding a cricket bat caused a commotion outside the Bridie O’Reilly Irish pub.

Footage by a stunned motorist captured guests jumping a barrier of the inner south-east pub, and saw more than 10 people involved.

Five men are seen attacking a man following a verbal row, prompting them to punch him multiple times in front of motorists and residents. 

More than eight men are then seen spilling onto Chapel Street, hitting each other and running down the road. One young man was knocked to the ground and left injured just metres from moving vehicles. 

Several young females were also involved in the brawl before it was broken up by other pedestrians. 

Paramedics were called to the scene just after 5pm, treating a woman and man both aged in their 20s.
