A tiger kidnapping or tiger robbery involves two separate crimes. The first crime usually involves an abduction of any person or thing someone highly values. Instead of demanding money, the captors demand that a second crime be committed on their behalf. The second crime could be anything from robbery, murder, to planting a bomb. A person or item held hostage is kept by the captors until their demands are met. The goal of the captors is to have their risky/dirty work performed by another person. The victims of a crime like this are less likely to report to authorities since they just committed a crime themselves.
Police have identified highly organised paramilitary training camps that prepare potential tiger kidnappers; one witness stated that trainees operate so cohesively that they are comparable to a SWAT team.
The practice began as a twist on a tactic used by the Irish Republican Army, which kidnapped people in order to coerce others into placing car bombs.
The first recorded crime that can be described as a tiger kidnapping occurred in 1972, but the term was coined in the 1980s and gained more widespread use in the following decade. Since tiger kidnapping is technically two crimes committed in tandem, statistics regarding their occurrence are difficult to compile. Tiger kidnappings have occurred in several jurisdictions, but are more common in the United Kingdom, Ireland, and Belgium. Examples include the Northern Bank robbery and Bank of Ireland robbery. According to International Herald Tribune, tiger kidnappings "have become common in Ireland, a close-knit society where criminals can closely track their targets" and "they have typically involved thefts below €1 million." After the 2009 Bank of Ireland robbery, Charlie Flanagan, a member of the Irish Parliament, remarked that “tiger kidnappings are taking place in Ireland... at a rate of almost one per week.”
