Violent clashes broke out between Brussels police and people gathering to attend a fake April Fool's Day festival on Thursday in violation of coronavirus restrictions.
Ilse Van de keere, spokesperson for the Bruxelles Ixelles Police, told CNN on Friday that 26 police officers and eight participants of the illegal event were injured when police tried to break up the gathering.
The windows of a police van were smashed and seven police horses were injured Van de keere said, and that 22 people were arrested.
Footage from the scene shows police officers on horseback appearing to strike participants with batons and spraying water cannons to try and disperse the crowd.
The hoax event, called "The Party," was widely promoted on social media networks as an outdoor festival in the city's Bois de la Cambre park.
A Facebook event page for the event boasted a lineup of "100s of DJs" and free admission for participants.
On March 17, the Brussels police posted a tweet warning potential attendees that the event was an April Fool's joke, adding that no authorization had been given and police would be present.
A number of anti-lockdown events and protests have taken place in Brussels this year with one protest on February 1 resulting in 488 arrests.
