Wikipedia
Gang rape occurs when a group of people participate in the rape of a single victim. Rape involving at least two or more violators (typically at least three) is widely reported to occur throughout the world. Systematic information and statistics on the extent of the problem, however is limited.
One study showed that offenders and victims in gang rape incidents were younger with a higher possibility of being unemployed. Gang rapes involved more alcohol and drug use, night attacks and severe sexual assault outcomes and less victim resistance and fewer weapons than individual rapes. Another study found that group sexual assaults were more violent and had greater resistance from the victim than individual sexual assaults and that victims of group sexual assaults were more likely to seek crisis and police services, to contemplate suicide and seek psychotherapy than those involved in individual assaults. The two groups were about the same in the amount of drug use and drinking during the assault.
Gang rape is sometimes referred to as "group rape", "party rape", or "multiple perpetrator rape" in scholarly literature.
