Molotov cocktails thrown after Sydney row

Molotov cocktails have been thrown at a group of people who were brawling in a Sydney square.

A man was also stabbed in the shoulder during the fight in Tom Uren Square at Redfern on Thursday night.

Police attended the scene after reports of a brawl at 9.15pm but found no one there.

About two hours later, two Molotov cocktails were thrown at a group of people in the same square, and a third about two hours after that.

Police say no one was injured.

It's believed the fire bomb incidents are connected with the brawl.

A 27-year-old man was arrested at a home in Morehead Street, Redfern on Sunday and charged with assault occasioning actual bodily harm.
