VICTORIA Police has confirmed it is investigating Dustin Martin over allegations he threatened a women with chopsticks, an investigation requested by the AFL.

The Richmond star has been the subject of a club and AFL probe since the allegations surfaced on Monday, but only now has the matter come under police scrutiny.

In a statement released on Thursday evening, the League confirmed it had instigated police action.

"The serious nature of the allegation requires that this matter be referred to the police," the statement read.

"If the investigation reveals threatening and violent behaviour, the AFL will take strong action."

The AFL indicated it would now wait for the police investigation to be completed before issuing any sanctions of its own against Martin.

The woman has alleged that Martin threatened to stab her in the face with chopsticks at a Chapel Street eatery.

Martin telephoned the victim to apologise, admitting he was drunk at the time.

"Police are investigating after reports a woman was threatened by a man at a Chapel Street restaurant in St Kilda about 9.42pm on Saturday," a police spokesperson confirmed.  

"The incident was not initially reported to police. 

"However, police are now aware of the incident and have identified the victim is a woman from Sydney.  

"The investigation remains ongoing therefore no further comment will be provided. 

"Anyone with information is urged to call Crime Stoppers."

Wait for the facts before judging, says disappointed Dangerfield

Richmond initially described the incident as a "hiccup", before taking a harder stance on Tuesday, calling it a very serious matter and planning to issue a sanction by the end of the week.

Martin has been training with his Tigers teammates this week.

The Tigers have said they won't be commenting until the police investigation is complete.
