When he [Hazrat Mahdi(as)] who believes sees the Dajjal, he will say: “O People! This is the Dajjal of whom the Messenger of Allah (saas) spoke.”  THE DAJJAL WILL IMMEDIATELY ISSUE HIS COMMAND REGARDING HIM AND that person will be stretched out on his stomach, after which he will say, “Take him and wound him.” And his back and stomach will be beaten and broadened. This time THE DAJJAL WILL CATCH HIM [HAZRAT MAHDI (AS)] BY HIS TWO HANDS AND FEET AND CAST HIM AWAY. People will imagine the Dajjal has cast him into the fire. But he has actually been cast into a paradise. 1

 
Our Prophet (saas) notes in this hadith that in the End Times the Dajjal will chain Hazrat Mahdi’s (as) hands and feet. It appears from this information in the hadith that at the time when Hazrat Mahdi’s (as) hands and feet are bound by chains he will be thrown into prisons and mental asylums.
