You'll need a character with the "Statue Pose" ability in their stats. now I didn't find a certain location for a character to have that but I can tell you where I did find one by luck at least. just right of the Tower Bridge in the dock area. (the far right bridge that connects Soutwark to Tower Hamlets district) the spawn is maybe randomized but you'll come across one for sure when you're doing other things. so just keep an eye. regardless, when you do find a character with that ability, you need to go on a killing spree and pop some innocent people to get that level 5 pursuit. then you need to lose the cops just for a little bit so you can press
go over to the Statue pose and you'll lose the cops after sometime.
EDIT: here is a video of possible spawn locations by Powerpyx.
