The administrative unit of the district jail and its female ward are functioning in 115-year-old dilapidated houses, posing serious risk to the officials, employees, and women prisoners.
The Public Works Department declared the two buildings abandoned on July 5 and November 1 last year, jail officials said.
"Following approval of the higher authorities concerned, the jail officials have already decided to shift all the 16 female prisoners to Sherpur District Jail. The work will be done within a few days," said Jailer Md Anwar Hossain on Thursday.
The buildings were constructed in 1899 as the sub-divisional jail of Jamalpur, then a sub-division under Mymensingh district.
After construction of necessary structures, one of the old buildings was turned to the female prisoners' ward, jail sources said.
It became dilapidated over years.
A female prisoner got injured, being hit by a chunk of plaster that fell off the roof on November 1 last year.
Informed by the jail authorities, the Public Works Department made a survey and declared the female ward abandoned on November 3.
Last year the jail officials sent a proposal to the higher authorities for reconstruction of the two dilapidated structures, but to no effect, Jailer Anwar said.
