What does mobber mean?
Mobber is an informal noun for a member of a mob, especially someone who participates in collective intimidation, violence, disorder, or theft. In British usage it often suggests rough or criminal character; North American dictionaries also record it, although it remains uncommon. The related verb “mobber” means to mob someone, treating the target as the object of intimidating crowd action. A mobber is not a formal title for a gang leader or an organized-crime figure: that role is more usually called a “mobster,” whereas a mobber is simply someone within the crowd. Modern speakers are more likely to choose “mobster,” “thug,” “hooligan,” or “mob,” depending on the intended sense. The word is useful for distinguishing an individual participant in mob action from the collective group and from the specialized criminal term “mobster.”
A member of a mob, especially an unruly or violent participant; a thug or hooligan.
"The police were looking for the mobber seen in the surveillance footage."
Informal and often derogatory; especially associated with British English.
To mob someone, especially by surrounding, intimidating, or attacking them as part of a crowd.

Rare and informal; usually describes collective intimidation or aggression.
The regular plural is used when referring to multiple members of a mob.
"The police identified several mobbers from the video footage."
A mobber is not the mob’s boss—just one member of the crowd behaving as the mob.

Where does mobber come from?
Mobber is an English agent noun formed from mob by adding the suffix -er, with a meaning equivalent to “one who mobs” or “one who belongs to a mob.” Mob itself entered English from French in the late sixteenth century and was used both for a general crowd and, especially in older usage, for a disorderly or violent crowd. Mobster and mobbish are later formations from the same English base; mobber itself has no separate non-English origin.
