In the immediate aftermath of the crash, Russell jumped out of his cockpit and approached Bottas’ car.
The drivers exchanged words before Bottas raised his middle finger and Russell slapped the Finn’s head.
After the race, Russell revealed that he had asked Bottas if he was trying to kill both of them, but the young Brit today issued an apology on social media.
“Yesterday wasn’t my proudest day,” Russell wrote.
“I knew it would be one of our best opportunities to score points this season and, when those points matter as much as they do to us right now, sometimes you take risks.
“It didn’t pay off and I have to take responsibility for that. Having had time to reflect on what happened afterwards, I know I should have handled the whole situation better.
“Emotions can run high in the heat of the moment and yesterday mine got the better of me. I apologise to Valtteri, to my team and to anyone who felt let down by my actions.
“That’s not who I am and I expect more from myself, as I know others expect more from me.
“I’ve learned some tough lessons this weekend and will come out of this a better driver and a better person for the experience.
“Now it’s full focus on Portugal and a chance to show what I’m really about. Thanks for all the messages, both positive and negative. They will all help me to grow,” he concluded.
