The FBI says Olumide Adebiyi Adediran fled Illinois shortly before his trial and has been wanted on a federal arrest warrant since January 2002.

The United States Federal Bureau of Investigation (FBI) has declared Nigerian-born Olumide Adebiyi Adediran wanted and announced a reward of up to $10,000 for information leading to his arrest and conviction.

According to the FBI, Adediran is wanted in connection with federal fraud charges dating back to 2001 and for allegedly violating the conditions of his release.

The agency said Adediran has ties to South Florida and is believed to have fled the Central District of Illinois shortly before he was due to stand trial.

The case dates back to August 2001, when Adediran allegedly attempted to withdraw money from a fraudulent cheque at a bank in Champaign, Illinois.

Investigators also allege that he used stolen personal information to open bank and credit accounts, leading to charges involving financial and identity-related fraud.

The charges against him included bank fraud, identification document fraud and credit card fraud.

The FBI said Adediran fled the Central District of Illinois in December 2001, shortly before his scheduled trial.

A federal arrest warrant was subsequently issued for him on January 2, 2002, and he has remained wanted in connection with the case.

The FBI's Springfield Field Office is investigating the matter and is appealing to members of the public who may have information about Adediran's whereabouts.

The agency urged anyone who recognises Adediran or has information that could help investigators locate him to contact the FBI or the nearest US embassy or consulate.

The FBI said information provided by the public could qualify for a reward of up to $10,000 if it leads to his arrest and conviction.

The case highlights the FBI's continued efforts to track suspects wanted in long-running federal investigations, including cases involving alleged financial and identity-related crimes.

Anyone with credible information is encouraged to contact the FBI directly rather than attempting to approach or confront the suspect.
