A WA Police spokeswoman said about 12.45pm on September 23, the 37-year-old victim was walking to his car behind Snap Fitness on Third Road when without provocation a man approached and punched him in the face.
‘The offender then walked away towards Jull Street,’ she said.
A passerby helped him before paramedics took him to Royal Perth Hospital.
Police believe the man pictured can assist with their inquiries. He is described as 30 to 40-years-old, about 180cm tall, olive-skinned and of average to heavy build, wearing a black jumper and black track pants with white stripes.
Anyone who can identify him or provide further information must call Crime Stoppers on 1800 333 000.
