Topeka ? State officials are investigating a Topeka juvenile detention facility after receiving an anonymous letter claiming boys are housed in “inhumane and immoral” conditions in a segregation unit.

Someone purporting to be a social worker at the Kansas Juvenile Correctional Complex sent the letter earlier this month to numerous governmental agencies.

It raises issues such as inadequate sleeping provisions, insufficient hygiene materials, a lack of medical treatment and placement of juveniles in isolation for long periods of time.

Corrections spokesman Bill Miskell says complaints against detention centers are common, and the letter’s claims are being investigated.
