A person who deliberately causes noise, damages public or private property, and disturbs public order.
example
Die Polizei nahm nach dem Fußballspiel mehrere Randalierer fest.
After the football match, the police arrested several rioters.
Usage tips
Word family
The word belongs to a family: the verb is 'randalieren' (to make noise deliberately and destroy things), and the noun for the act is 'die Randale' (rioting). A 'Randalierer' is therefore a person who riots.
EXAMPLE
Die Gruppe begann nach Mitternacht zu randalieren.
The group began to riot after midnight.
Word formation
The ending '-er' is attached to the stem of the verb 'randalieren' (to riot) to refer to the male person who carries out this action. This pattern is very productive in German.
EXAMPLE
Ein einzelner Randalierer hat mehrere Fensterscheiben zerstört.
A single rioter destroyed several windowpanes.
Typical contexts
The word 'Randalierer' (rioter) often appears in news reports and reports about riots at large events. Typical contexts are football matches, demonstrations, or New Year's Eve celebrations.
EXAMPLE
Nach dem Fußballspiel kam es zu Auseinandersetzungen zwischen Fangruppen und Randalierern.
After the football match, there were clashes between fan groups and rioters.

Randalierer vs Demonstrant
demonstrator
'der Demonstrant' and 'der Randalierer' can both appear in reports about public gatherings, but they do not mean the same thing. A 'Demonstrant' takes part in a demonstration and publicly shows their opinion. A 'Randalierer' disturbs public order, deliberately makes noise, or damages things. The words can be confused when there are problems at a demonstration. The important point is: demonstrating is not automatically rioting. Use 'Randalierer' only when someone is truly destroying things or causing violent disruption.
Randalierer
Nach dem Spiel warf ein Randalierer eine Flasche gegen ein Schaufenster.
After the game, a rioter threw a bottle at a shop window.
Demonstrant
Der Demonstrant sprach ruhig mit der Polizei und blieb auf dem Gehweg.
The demonstrator spoke calmly with the police and stayed on the sidewalk.
