A garbage collector was injured as a bomb exploded inside the outer boundary of Jessore Central Jail on Wednesday.
The injured Jahidul Biswas alias Kalu, 40, used to collect garbage pulling his three-wheeler.
The victim said that he found a white plastic pot near the staff quarters of the jail in the afternoon.
As he hit a coconut tree with the pot, it suddenly went off with a big bang, wounding his right hand severely, he said.
Jailer Abu Taleb said that though jail was a restricted area for others, Kalu normally came inside the outer boundary for collecting waste and plastic materials as his father was a prison guard. ‘We don’t understand how the bomb came inside the jail. Police are investigating the matter,’ he added.
Kalu was admitted to Sadar Hospital.
