A Melbourne hip-hop artist is wanted for questioning over a series of armed robberies and carjackings.
Police believe Corinthian Morgan, who performs as Mr Morgz, could be behind an attempted carjacking which left a 70-year-old woman with cuts and bruises.
A man fitting Morgan's description threatened the woman with a sawn-off shotgun in the Preston Market car park on January 7, police say.
The pair struggled and the car key snapped off in the ignition.
The man then pushed the woman to the ground and fled with her handbag.
Morgan could also be linked to an attempted carjacking at Reservoir in late December, in which a man armed with a tomahawk approached a family seated in their car, according to police.
The driver sped away when threatened.
Police are also linking him to similar offences in Shepparton.
He could still be in possession of the sawn-off shotgun and his behaviour could become more erratic, Detective Senior Constable Meaghan Briggs said.
"These incidents have all involved vulnerable people, often women, people on their own," Det Snr Const Briggs told reporters on Wednesday.
"We don't want to alarm the public about it but while he is at large there is the risk of another offence occurring."
Morgan, 27, failed to appear at Melbourne Magistrates Court in October in relation to charges of robbery and intentionally and recklessly causing injury.
He is about 190cm tall with a medium build, olive complexion and a tattoo on the left side of his neck saying `Mr Morgz'.
