A Melbourne teenager has been missing for two months, sparking a police appeal for public help.
Christiaan, 14, was last seen in Pascoe Vale on Saturday March 20, carrying a small suitcase.
His mother Sauileone has appealed for her son to make contact, and for anyone who has seen him to call Victoria Police.
"Please come home, we love you and we miss you, please come home," she told him at a press conference on Friday.
Detective Senior Constable Craig Buchan said police are especially concerned because of his age and the time he has been missing.
"It is concerning and it is baffling that we haven't had any piece of information just yet," he said.
He said Christiaan does not have a phone or any social media accounts, and does not have a debit card or bank account police could use to gain clues about his whereabouts.
He is an avid gamer and likes Youtube, and it's believed he had only his clothes and a laptop with him when he left.
Christiaan left his Pascoe Vale home at about 7.30am on March 20 after a family gathering the previous night.
"He's a great kid, super smart ... he's super fit, there was no indication of anything going on from my discussion with friends and family," Detective Buchan said.
Police have been searching the Melbourne CBD, suburban Broadmeadows and Pascoe Vale, and the NSW town of Griffith where his family has some ties.
The teenager is about 183cm tall with short black hair and a solid build.
