Metro Trains' authorised officers have come under fire for using excessive force to detain a schoolboy at Windsor station.

In a video posted on YouTube, two male officers can be seen pinning the student by his arms over a low wall on Wednesday morning.

The boy can be heard shouting "f---ing get off me", "let me stand up" and "what are you trying to do?" while flailing his legs in an attempt to get free.

The officers refuse to let him up saying he had "resisted arrest".
