Complete 10 Crowd Events.

In order to get this achievement you must complete 10 crown events.

1. When you are roaming around Paris you will see these crowd events appear randomly, they can be anything from chasing down thieves or fighting off criminals.
2. The best thing to do is run around the streets and complete them as you come across them.
3. All you have to do is simply kill criminals or chase a thief, do this 10 times and you get your achievement.

The best place to do this is in a highly populated area of the map, around Notre Dame etc...
You get an achievement and a IG reward after completing 10 so it is well worth it.
