Police are investigating two separate knife attacks in Albion Park and Wollongong on Friday night.
About 9pm, a 37-year-old man was walking home from the Albion Park Hotel when he was allegedly confronted by three males at the intersection of Terry and Church streets.
The victim was then punched in the head and attacked with a knife.
He was left with a slash wound to the hand, a small facial cut and minor lacerations of the abdomen.
Paramedics treated the victim for knife wounds and an unrelated medical condition before transporting him to Wollongong Hospital.
Police are also trying to locate a dog walker accused of stabbing a man in an unrelated attack on Friday night.
Police say the man was walking his dog on a lead along Church Street in Wollongong shortly after 6pm when he approached a 44-year-old man and stabbed him in the chest.
The 44-year-old was talking to a taxi driver in the moments before the alleged attack.
He reported the incident to police about two hours later and was transported to Wollongong Hospital with non-life threatening injuries.
Police say the attacker fled the scene.
He is described as 180 centimetres tall with long, grey hair.
He wore light blue jeans and a blue and white chequered shirt.
