Two former Tulsa police officers are back in the Tulsa County jail.
Harold "H.R." Wells and Jeff Henderson are serving time in federal prisons after being convicted as part of the corrupt cop investigation last year.
They were brought back to Tulsa Thursday after receiving subpoenas to testify.
Harold Wells was subpoenaed in the case of a man who pleaded guilty to drug charges 15 years ago but later wanted to take it back, saying he was coerced. And Jeff Henderson is to testify in the case of another convicted drug dealer who wants a lighter sentence.
Both cases were years before the investigation into Tulsa Police corruption began.
Both Wells and Henderson maintain they are innocent.
