vb. (present participle of tiger kidnap English)
Wikipedia
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.
