"Pursue Itachi" (イタチを追え, Itachi o oe) is chapter 365 of the original Naruto manga.
While Sasuke is resting, Karin senses Team 7 and Team 8 approaching their location. Knowing they have been found, Hebi starts moving. To get the Konoha ninja off of their tail, Jūgo tears up one of Sasuke's shirts and gives it to a flock of birds to make following Sasuke by scent useless. When the Konoha ninja notice this, Naruto creates a group of shadow clones to follow all of the Sasuke trails. One stumbles across Itachi, who asks to speak with him.
