What is a word for a punishment given by people without proper trial instead of the court?

Is there a word that describes the giving of punishment (usually stoned to death) of a criminal by the local people near where the crime happened?

A typical example would be when a thief in a village steals a motorcycle, and then gets caught by the angry mobs, and then usually the thief gets either killed by the mobs or beaten badly without proper hearing and trial, usually until the police intervene.

I've tried searching for "trial by the mass" (but apparently Google found mass trial instead), "public trial" (but apparently it means something different), "trial without hearing" (but the results are not what I'm looking for), "punishment by the mass" (but Google found capital punishment and collective punishment instead), and so far, nothing gives me a word for punishment by the public/mass.
