In-charge chief judicial magistrate Sanjay Kymar Jha sent Rocky to judicial custody when he was produced by the police and was later taken to Gaya central jail.
Rocky, who went missing since the incident on Saturday, was arrested from his father's mixer plant in Gaya district earlier in the day.
His father Bindi Yadav and Manorama Devi's bodyguard and police security personnel Rajesh Kumar, who were arrested on Sunday for allegedly helping Rocky to escape and was sent to 14 days judicial custody yesterday, are also lodged in the same jail.
While Chief Minister Nitish Kumar had strongly condemned the incident and asserted that nobody could escape the "long arms of law", opposition BJP claimed that "jungle raj" had returned to the state.
