"On 22 September 2014, another Dutch news site
reported that three arrests in total were made after the incident (but again, no mention of "Muslim" teens or Western attire appeared in the report):
The police arrested a third suspect for the assault of a 15 year old girl from Beverwijk.
This suspect is a 15 year old boy from Heemskerk. The other two suspects, two boys (14 and 15 years old) from Heemskerk and Beverwijk, were arrested on Thursday September 18th. They will appear before the magistrate today.
The police are currently investigating the cause of the conflict.
Finally, a 28 January 2015
article reported that the boys had been sentenced to community service, but still included no mention of religion or expectations of female modesty:
Two boys, aged 14 and 16, were sentenced to 80 hours of community service for assaulting a 15-year-old girl from Beverwijk in September. The incident in IJmuiden, Noord-Holland was caught on tape and the video soon went viral.
When determining the punishment, the severity of the act needed to be taken into account, according to the court statement.
Both parties were surrounded by a large group of young people who knew in advance there would be a fight. This created a charged atmosphere that influenced the behavior of the accused and the victim, said the court.
So while the video in question depicts an actual altercation that occurred in the Netherlands, the clip was later "rediscovered" and repurposed as part of a subsequent, unrelated debate about Muslim refugees in Europe. Prior to September 2015, no descriptions of the video included any of the details about "Muslim teens" objecting to a woman's attired that were attached to later iterations — those claims were apparently fabricated to generate outrage-based shares."
