(PhatzRadio / CBC Sports) — Louisiana State Police Col. Mike Edmonson says he still has an investigator working with the FBI on wiretapping allegations involving the New Orleans Saints, but adds that no evidence has been turned over to federal prosecutors at this time.

Authorities have been working on the case since April, when ESPN, citing anonymous sources, said Superdome wiring was rigged so Saints general manager Mickey Loomis could listen to opposing teams’ radio communications during games.

Loomis and the Saints have denied those allegations, and the Saints have hired the firm of former FBI director Louis Freeh to do its own investigation.

Edmonson says his investigator has been conducting interviews along with FBI agents. However, Edmonson says it is too early to discuss whether those interviews have produced any credible leads.
