At least one person has been charged.
A 22-year-old P-plate driver from Mount Druitt will face court in November.
He's been charged with several driving offences, after allegedly doing burn-outs, and also reportedly accelerating at police officers in some of the crowds.
The Panthers won their third NRL Premiership last night, defeating the Rabbitohs 14-12.
It was the Penrith club's second grand final in a row, after losing to the Melbourne Storm last year.
