Wenger was subsequently charged by the FA after the referee's report was submitted and he has now been given a three-match touchline ban.
The Gunners boss has also been fined £40,000 for his behaviour, the FA has announced.
Amazingly, that might not even be the last of the disciplinary action against Arsene Wenger.
Mike Dean pulled up Calum Chambers for an alleged handball, which allowed Jay Rodriguez to convert from the spot and snatch a 1-1 draw for the Baggies.
Not only that, the FA have asked for information on that too.
Macron to Erdogan: 'Democracies must respect rule of law'
Erdogan made the remarks during his meeting with members of the Movement of the Enterprises of France, a Paris-based federation. Turkish President Recep Tayyip Erdogan on Friday called on French businesses in Paris to take part in Turkey's economic growth.
Describing the incident, Wenger claimed that the decision was a "farce".
Wenger exchanged frank words with referee Mike Dean after the match, an argument that continued into the referees' changing room. "That is a concerning coincidence for me". The regret we have is we were first to score and after that we have a farcical decision.
Currently, Arsenal are on 39 points and sixth in the Premier League.
"We looked like we were mentally shot and could have lost the game - we had the resources to come back to 2-2".
"They want to see: 'Come on, let's get on with it and play.' That's our responsibility". Maybe it was a fair result. Look since the start of the season; it is what we have to take. Arsenal were on the end of another controversial penalty decision, this time from referee Anthony Taylor, and with the governing body already requesting that he explain his comments in relation to that fixture, he could face more time away from the touchline. "I'm happy with the quality of our games".
