The government of the United States has launched an investigation into policies affecting inmate placement in women’s prisons, following safety concerns raised in some facilities.

The probe, led by the Department of Justice, will examine selected correctional centres in California and Maine where complaints have been reported.

Officials say the review will focus on whether prison authorities have upheld the rights and safety of inmates under existing laws and regulations.

The investigation follows advocacy campaigns by some groups calling for a closer look at housing policies and their impact on prison conditions.

Authorities will assess claims of misconduct and determine whether any constitutional protections may have been breached in the process.

The outcome of the inquiry could influence future policies on inmate placement and safety measures across correctional systems in the country.
