When did Itachi plant his crow inside Naruto?


We all know that Itachi had the left eye of _Shisui_ which had the
_Kotoamatsukami_. This was planted as the eye of one the crows of Itachi and
the crow was planted inside Naruto, to counter Sasuke's _Mangekyō_ , if ever,
he turned against the village.

My question is, when did Itachi plant his crow inside Naruto and how did he do
that?! Did he inject it inside Naruto, or planted it using Genjutsu, or
something like that?




Itachi stores the crow inside Naruto in chapter 403, during the Itachi Pursuit
arc.  
Itachi used a shadow clone to talk to Naruto, who wasn't willing to listen. As
such, Itachi was forced to use a Genjutsu in order to make him listen.

He uses a Genjutsu as a distraction:

And then the crow is stored (physically, I think) inside of Naruto:
