To drag his lying ass back to his padded cell

from Eminem – Backstabber Lyrics on Rap Genius

Meaning

Eminem is determined to get this guy back in prison. The fact that it was a padded cell, rather than a normal jail, meant it was a mental prison or insane asylum. If he’s going after his “lying ass” this means the perpetrator convinced his jailers he was mentally stable so they’d let him go. Now he’s free, and just as dangerous as before.

This is another reference to Champtown’s music video.
At 1:00 the doctor literally throws Champtown into his padded cell.
