Wide-spread riots broke out in London, England last week.
People ran into the streets, breaking store windows and stealing merchandise (known as “looting”), and setting fires to buildings and cars.
Hundreds of people have been arrested and at least five people died in the riots.
There are many different reasons people joined the riots.
Some people looted because they thought they could get away with it in the crowds.
Some rioted because everyone else around them was doing it or they considered it fun.
