Police are appealing for help to locate two people who’ve been reported missing by their families in Newcastle.

30-year-old Katrina Johnson last made contact with her family on Thursday March 6 and could be in the Northern Beaches area of Sydney.

She’s described as being Caucasian with a thin build and pink and blue hair – she also has several tattoos over her body.

Meanwhile, 27-year-old Logan Wilson was last seen at New Lambton on Monday this week and his disappearance is out of character.

Logan is described as being Caucasian, about 175cm tall with a medium build and brown hair.
