He said the EM pilot project will begin in November and may be expanded to 6,000 inmates in the next fiscal year.
All departments under the Justice Ministry have been instructed to propose solutions to overcrowded prisons nationwide, he said, adding that the Corrections Department is currently supervising 270,000 prisoners.
He said the newly-built prison for juvenile offenders in Lopburi could not be operated due to insufficient numbers of wardens, consequently intensifying the problem of overcrowded prisons.
Suchart Wongananchai, Corrections Department director general, said the electronic monitoring devices would be introduced and used on four categories of inmates including the terminally-ill and elderly prisoners, inmates with mental health problems, those who must care for their parents, spouses or children, and patients with chronic illnesses.
He said the Corrections Department has coordinated with the Public Health Ministry to provide treatment to inmates at prison medical centres.
A recently-constructed Corrections Department hospital could accommodate 500 beds, but can take only 250 patients due to inadequate medical staff.
