Officers at a juvenile detention center in Dallas kept kids isolated for days and falsified logs of observation checks and school attendance, an investigation from the Texas Juvenile Justice Department found.

“They spent the vast majority of their days inside their cells, sometimes up to 24 hours a day, without regular access to education, large muscle exercise, outdoor recreation, or showers,” state investigators wrote in a report released Monday.

This week’s report comes after the U.S. Department of Justice found unconstitutional conditions at all of Texas’ five juvenile detention facilities last month. They noted abusive and poor conditions and listed many remedial measures including limiting periods of isolation. Investigators found other wrongdoings such as pepper spray use on children and failure to apply sexual abuse reduction measures.
