PER USER data usage through Mikrotik

Is it possible to measure the data an specific USER?

I have a client that owns a Mobile Home Park and he offers FREE wifi
my company provide IT services for him

the owner has COMCAST and we have a Routerboar RB951 Series behind it.

Apparentaly one of the residents its ABUSING the network and downloading copy right movies

and we wanna track him down

any ideas?

Thank you so much in advance!
