I think he just kind of ended up there after his parents died and he went pretty much insane and turned himself into a puppet.
Sasori
They met when Pain sent Sasori, Kisame, and Itachi to find Deidara to recruit him for the Akatsuki. Once Deidara joined the Akatsuki, he and Sasori became partners.
Before Sasori became a member of the akatsuki, Sasori was a member of the sand village.
Sasori was in his 20s when paired with Orochimaru.

Some say that the fourth was the leader of the Akatsuki clan, and some pics show Naruto as one of the Akatsuki, but no Naruto nor the fourth(his father),could be apart of the Akatsuki, because Naruto hates the Akatsuki.Right now in Naruto Shippuden, Gaara fought Diedara and lost and Deidara took Gaara to Sasori in the Akatsuki's lair sthey could take Gaara's demon out of him.
Deidara and Sasori first meet in Episode 2 of Naruto Shippuden, titled "The Akatsuki Makes Its Move". In this episode, Deidara is sent by the Akatsuki to capture Gaara, while Sasori observes from the shadows.
He was kidnapped by Sasori to be turned into a human puppet
SPOILER ALERT Depends on what you are asking. His partner in the Akatsuki is Kisame Hoshigaki. I assume that is what you mean.
Do you mean the akatsuki?
