Forty-three people were detained by police in Brussels on Saturday after a riot broke out following a fatal accident between a police vehicle and a young man on a scooter, authorities said.

The unrest began on Friday night when a police patrol in Anderlecht, a district of Brussels, attempted to stop a 19-year-old driving on a scooter.

The police gave chase, but the scooter collided head on with a second police vehicle killing the scooter driver on the spot.

After several incidents on Friday, riot police were called in to disperse young protesters who had gathered on Saturday following a call on social media to demonstrate over the death. 

The mayor for the district, Fabrice Cumps, stated that two police officers suffered minor injuries in Saturday's incidents, one hit by a projectile.

Several protesters also suffered minor injuries, he said. 

Cumps said the situation was "clearly under control" but that police remained mobilized in case of any more incidents.

The mayor said he met with the family of the motorcyclist on Saturday and that he believed the death was being used as a false pretext by trouble-makers. 

Belgium has been on lockdown for four weeks in an effort to stem the spread of the coronavirus outbreak.
