EMPORIA, Kan. (AP) — A former Emporia State University assistant professor has refiled a federal discrimination lawsuit against the university and several administrators, and his wife has filed a separate lawsuit also claiming the school discriminated against her.

Melvin Hale and his wife, Angelica, who are black, allege in lawsuits filed last week that the school discriminated against them after they complained about a racial incident in April 2015 while they worked in the School of Library and Information Management. The Hales said school administrators originally did nothing, then conducted a biased investigation and retaliated against them. Both lost their jobs and they no longer live in Emporia.

Melvin Hale’s original lawsuit was dismissed at his request in October.

Emporia State says an investigation found no evidence of a hate crime against the Hales.
