Prosecutors have charged two city correction officers with smuggling cocaine and oxycodone into Rikers Island.

Jail guards Steven Dominguez and Divine Rahming were arraigned Tuesday on conspiracy, bribery and drug possession charges in state Supreme Court in Manhattan.

They both pleaded not guilty. Defense attorney Peter Troxler says he believes Dominguez is innocent. Rahming's lawyer hasn't returned a call. A union spokesman declined comment.

They were arrested by the Department of Investigation last month. An inmate and his girlfriend are also named in charging documents.

Special Narcotics Prosecutor Bridget Brennan says Dominguez and Rahming met with undercover agents multiple times to exchange drugs and money and were heard discussing deals on their cellphones.

Prosecutors say a former jail guard was arrested Monday in an unrelated but similar scheme.
