Islampur, Feb. 6: An undertrial Bangladeshi held for alleged infiltration escaped from the correctional home here this afternoon after scaling a 40-foot wall.
Sources said there were 185 male inmates in the jail and the post-lunch count of heads conducted around 2pm showed everyone was present.
Around 2.40pm, warders saw the cell where Mohammad Ibrahim, 25, was kept empty.
A search was conducted and the warders found a pile of rubble at the rear end of the home near the boundary wall. A blanket with bricks tied on both ends was also spotted on the other side of the wall.
An alarm was raised and the prison siren activated.
Jail sources said it was suspected that the youth had managed to accumulate the rubble and he must have got help from outside as someone was needed to hold on to the blanket from the other side.
Subdivisional officer of Islampur Samanjit Sengupta, also the superintendent of the home, and assistant inspector general of prisons Kamal Mukherjee visited the home.
"We are investigating how the prisoner escaped and if there were lapses on the part of the staff," Mukherjee said.
Ibrahim had been taken to the correctional home on October 7, sources said.
He was brought in by the Goalpokhar police after the Border Security Force caught him roaming along the India-Bangladesh border without valid papers.
Ibrahim is a resident of Balidangi village in Bangladesh's Thakurgaon district.
