Is bullying usually carried out by an individual or group?

In the 1990s, a study of 25 secondary schools in England found that peers can encourage bullying and so make the situation worse (Glover and others, 2000). It was found that it was three times more likely for a group of boys to carry out a physical or verbal attack than a boy on his own. Girl bullies were twice as likely to operate in a group than on their own.
