WICHITA, Kan. (AP) — Wichita’s city attorney says the city’s police department didn’t violate any laws by keeping decades-old sensitive cases in a limited-access file separate from other investigations.

The Wichita Eagle reports the files include those dealing with police officers and city employees.

City Attorney Jennifer Magana’s three-month internal review came after City Manager Bob Layton said he became aware of the so-called “confidential” files dating to the 1980s.

Most police records are accessible by more than 800 Wichita police employees. But the limited-access files are available to 92 people across five agencies or departments.
