Most kidnappings occur when the target is either alone, or lured to their abductor(s). The victim may also be coerced into surrendering themselves to protect their friends, or in exchange for someone else.
This abduction occurs when the victim is taken in the presence of their friends, without the kidnapping being seen. The most common reason is because the victim is either standing near the back of the group, or trailing far enough behind for the abduction to go unnoticed by their friends. Alternatively, the victim may be positioned off to the side, just outside their friends' field of vision.
Regardless how it occurs, it allows the culprit to demonstrate their stealth, cunning, and brazenness by committing the act right under their enemies noses, which they're all but certain to boast about later. And don't be surprised if the perpetrator turns out to be a Phantom Thief, an enemy spy, or worst of all... a ninja. It can also be done by heroic characters, usually to either steal the victim's clothes, or for interrogation.
Since the audience is often meant to be as surprised as the kidnap victim, examples of this trope will contain mostly unmarked spoilers.
