EAST PROVIDENCE, R.I. (AP) — Rhode Island state police say they've closed an investigation of the suspension of East Providence's police chief after finding no wrongdoing.

State police looked into allegations that some City Council members had unlawfully influenced Town Manager Peter Graczykowski to suspend Police Chief Joseph Tavares in April, in exchange for the council renewing Graczykowski's contract. Graczykowski denies the allegations and says he works at the will of the council without a contract.

State Police Deputy Superintendent Michael Winquist told The Providence Journal that investigators have exhausted all leads in the case.

Tavares was suspended with pay on April 15 based on undisclosed allegations by the police union, which approved a no-confidence vote against the chief in June. The state-appointed Budget Commission for the city reinstated Tavares effective May 29.
