Police are appealing for public assistance to help locate a missing 42-year-old Wallsend man.

Gregory Rush works at Strathfield and resides at Belmore, in Sydney’s south-west, during the week. He returns to his mother’s address at Wallsend on weekends.

On Monday 11 January, Mr Rush didn’t arrive at work as scheduled and a check of his Belmore residence found no sign of him.

He had not been at this mother’s address either.

Police and Mr Rush’s family are concerned for his welfare as his disappearance is out of character.

He is described as 180cm tall, with a slim build, black curly hair and green eyes. He has tattoos of eagles on his upper back and upper right arm. .

Mr Rush’s car, a white Ford with NSW registration plates – UKR 765 – is yet to be located.
