New South Wales police were called to a fight between two members of the controversial Sydney band Sticky Fingers on Saturday afternoon after lead singer Dylan Frost, 28, and bassist Paddy Cornwall, 29, allegedly came to blows.

The two men began fighting just before 5.30pm on Faversham Street behind the Marrickville Bowling and Recreation Club, where the pair had been drinking, police said.

An ambulance was called to treat Frost, who was suffering bruising and redness on his face.

A police spokeswoman said the "younger man" – Frost – was searched in the ambulance before being taken to hospital and allegedly found with a knife, which was seized.
