A man who helped dupe dozens into sending millions of dollars to people posing as U.S. military personnel in an online dating scheme has been sentenced to 14 years in federal prison.

Rubbin Sarpong must also pay over $3 million in restitution to 36 victims under the sentence imposed Tuesday, as well as more than $385,000 to the Internal Revenue Service.

The 38-year-old had pleaded guilty last November to multiple counts.

Federal prosecutors say the scheme ran from January 2016 to September 2019. They say Sarpong and his co-conspirators, several of whom live in Ghana, set up phony profiles on online dating sites using fictitious or stolen identities and posing as U.S. military personnel.
