A police officer clocked driving at more than double the speed limit in Melbourne's south-east has been suspended with pay.
Highway patrol recorded the leading senior constable travelling at 122km/h in a 50km/h zone on Garden Road, Clayton, about 10.15pm on Friday.
His car will be impounded for 30 days and he is expected to be charged on summons with driving offences, a police spokeswoman said.
The ethical standards command will investigate the incident and has suspended the officer with pay.
The officer will also face an internal disciplinary inquiry.
Road Policing Command Superintendent Neville Taylor said anyone caught driving dangerously would be held accountable.
"We expect all motorists to behave responsibly on our roads, regardless of who they are," he said.
"No one is above the law and if you do the wrong thing you will be caught and penalised."
