A popular karaoke bar in Sydney's CBD has been targeted in a Molotov cocktail attack.
It was business as usual at Karaoke World on Elizabeth Street last night, when at nine o'clock a group stormed into the bar and began throwing flaming objects across the room.
The Molotov cocktails set the place alight, but luckily the fire sprinklers inside the business kicked in and extinguished the flames immediately.
No-one was injured, but the building has sustained significant damage.
Police say a group of teenagers was behind the attack.
They're now combing over CCTV footage of the firebombing incident.
