A Nigerian, Daniel Adekunle Ojo, who had spent less than 14 months in the United States, has been arrested in Durham, North Carolina and charged with fraud and identity theft offences

The offences stemmed from Ojo’s phishing scheme, using an AOL and GMail email accounts that targeted school districts in Connecticut and Minnesota in an effort to get employees’ personal information and file bogus tax returns.

His arrest was announced Friday by Deirdre M. Daly, United States Attorney for the District of Connecticut, Patricia M. Ferrick, Special Agent in Charge of the New Haven Division of the Federal Bureau of Investigation, and Joel P. Garland, Special Agent in Charge of Internal Revenue Service Criminal Investigation in New England

Following his arrest at his Durham residence, Ojo appeared before a U.S. magistrate judge in Greensboro, N.C., and was ordered detained pending his transfer to the District of Connecticut.

Prosecutors said a school district employeein Glastonbury, Connecticut, received an email in February that appeared to be sent by another employee, who asked for tax information for 1,600 school district workers. The worker who received the email then forwarded the information, which was used in the scheme to file 122 bogus tax returns seeking nearly $600,000 in refunds, authorities said.

Officials said the Internal Revenue Service processed about six of the fake returns andelectronically deposited nearly $37,000 in refunds to various bank accounts.

Investigators linked the email sent to the employee to Ojo, prosecutors said.

Officials also believe Ojo was involved in similar email schemes targeting school districts in Groton, Connecticut, and Bloomington, Minnesota.

In March, a Groton school employee emailed tax information of 1,300 employees in response to an email that appeared to be from the superintendent of schools. Authorities said the information was used to file about 66 fraudulent tax returns seeking about $364,000 in refunds.Officials said the fake returns weren’t processed because they had been flagged as being part of an identity theft scheme after school employees discovered the problem.

Prosecutors also said they linked the email account used by Ojo to a similar scam that obtained tax information for about 2,800 school employees in Bloomington earlier this year.

Eric Placke, a federal public defender in North Carolina who represented Ojo only forhis initial court appearance, declined to comment Friday. It’s not clear who Ojo’s attorney will be in Connecticut.

Authorities said Ojo entered the U.S. in May2016 on a visitor’s visa and failed to leave on his scheduled departure date in June 2016.

Daly urged the public to double-check links and email addresses before clicking on and responding to them, to avoid becoming an identity theft victim.
