Clashes outside the Johan Cruyff Arena see Dutch police spray Ajax ultras with a water cannon.

These intense scenes were taken just before Ajax's Champions League match with Juventus on Wednesday (April 10).

According to the filmer: "The police intervened, prohibiting all pyro (flares) using a water cannon and horses, which injured a number of fans."

Fans of Ajax have a well established history in organising
pre-match events called a "corteo" or "entrada"

Thousands of fans used to participate and create
a fabulous atmosphere outside the stadium
that includes flares, fireworks and chanting

Prior to the Champions League match against Juventus (Apr 10, 2019),
Ajax fans had organised another of these events,
but the police intervened - prohibiting all pyro and
using a water cannon and horses, which injured a number of fans
