The Lensois public had not known a derby at home for more than 10 years.
And the supporters' match, in a game that was logically sold out, degenerated at half-time.
Several dozen members of the Marek stand, a stand for Lensois supporters, descended on the lawn and headed for the Lille parking lot.
Calm returned after about ten minutes.
But according to information from Amazon Prime Video, a crisis unit has been triggered.
Referees and match delegates must meet to decide what to do next.
Contact with the local authorities must be established to decide whether or not to resume the match.
