He marched straight over to Ocon and shoved him several times as his foe pleaded his innocence before Verstappen stomped away while continuing to point and shout at the Frenchman.
Ocon was handed a 10-second penalty after he was deemed to have caused the collision.
Hamilton took advantage of the clash by claim victory and help Mercedes to retain the constructors’ championship.
Verstappen, who ended up finishing second, was found guilty of "starting an altercation, pushing or hitting Ocon forcefully several times in the chest", and failing to "act as a role model to drivers of all levels".
As such, the Dutchman must now serve two days of public service at the FIA's request within the next six months.
Following their explosive altercation, Ocon called Verstappen a "lunatic" on French TV and stood by his move.
He said: "With Max it did not work out.
"That's one thing. But what is worse is Max's behaviour afterwards - being violent, pushing me, wanting to punch me. The FIA had to stop him.
"That is not a professional way of handling things. I would do the same again."
Verstappen, his face still red with anger in the post-race press conference, said: "He (Ocon) has always been an idiot.
"I was trying to do my job, and then suddenly a backmarker is racing you and taking stupid risks."
Verstappen's Red Bull team principal Christian Horner added: "Max has been pretty restrained to be honest with you. It cost him a Grand Prix victory.
