The hangman, whose identity has been kept secret due to security reasons, arrived at the Central Prison a week ago as part of a 20-member team of prison personnel from Yerwada Jail.
He had pulled the lever to hang on Kasab -- the only perpetrator of 26/11 Mumbai attacks caught alive -- on November 21, 2012.
Jail Superintendent of Yerwada, Yogesh Desai, who had led the team during Kasab's execution in Pune, was transferred to the Nagpur Central Prison a few months back, apparently to oversee Yakub's hanging.
According to jail officials, the constable executed the hanging with "clinical precision".
Also, another constable from Yerwada was brought here a week ago and trained with two others to assist the hangman. The other members of the team were entrusted with the task of preparing the drop and the platform in the execution yard.
Nagpur and Yerwada are the two Central Prisons in Maharashtra equipped with hanging facility.
The previous execution at Nagpur jail was carried out in 1984, when two brothers from Amravati had been hanged for murder.
Memon was hanged shortly before 7 am -- less than two hours after the Supreme Court dismissed his final appeal against his execution in an unprecedented hearing held within the court premises in Delhi in the middle of the night.
