Yes.
There is a lease-time associated with DHCP so at some point in time, his PC will broadcast a DHCP Discovery packet. The router will see it and eventually assign it a new IP and he'll be back on before you even know it.
You will either have to block the ports where he's using to tie up the bandwidth or you block him completely from your router through a MAC filter. Another option is to setup throttling/QoS on his specific PC. There are other ways but I'm just throwing these ideas out there.
