Jail Super Jahanara Begum came up with the information saying that Abu Bakar Siddique remained missing since the evening.
The jail authorities did not find him inside the jail on Friday morning.
Siddique, hailing from Abad Chandipur in Shyamnagar upazila of Satkhira, was shifted to the Kashimpur Central Jail from Rajshahi as a death-row convict in 2011.
On July 27, 2012, a court commuted the death sentence and gave him life imprisonment in a case.
Earlier on May 13, 2015, Abu Bakar remained missing from jail as he went into hiding inside the jail. Later, the jail authorities found him from inside a septic tank the following day.
The authorities concerned also suspected that he might have kept him hidden inside the jail like before.
Commissioner Anwar Hossain of Gazipur Metropolitan Police said the jail authorities conducted a search operation inside the complex and if they failed to find him then they will inform him officially. A general diary will be lodged after that.
