Two senior constables aged 34 and 45, were suspended from duty as of Tuesday 8 February following a Narre Warren South arrest.
A 58-year-old man was injured during an arrest in Narre Warren South shortly before 1.30am on Friday, 4 February.
The man was taken to hospital for treatment and has since been released, Victoria Police said in a statement.
The two officers involved in the arrest were from the transit and public safety command.
Victoria Police notified The Independent Broad-based Anti-corruption Commission (IBAC) when a Professional Standards Command investigation was launched.
IBAC works to expose and prevent use of force by police and will oversee the Victoria Police investigation.
IBAC reviews the outcomes of Victoria Police internal investigations to check they have been investigated thoroughly and fairly, which may result in recommendations for Victoria Police to strengthen its policies and procedures to address police misconduct issues.
