When does 'citizens arrest' become kidnapping?

When they kidnap them and take them elsewhere.

Well ish, you can make a citizens arrest and take them to a police station
or magistrate to face charges.

Mind you the whole thing around "citizens arrest" is right tangled mess:

As these two put one chap in a van took him to his mates then had a fight
no wonder they got done for kidnap. If they just used reasonable force
(what ever that is) to hold him, called the police and waited they
probably wouldn't have attracted the kidnap charge. They might have got
unlawful arrest instead...
