British police say two men have been jailed for a scam to defraud Olympic officials of millions of dollars.

Metropolitan Police say the two were found guilty of money laundering and sentenced Tuesday to up to four years and six months.

Abayomi Olowo and Ayodele Odukoya were arrested in 2010 after the Olympic Delivery Authority became suspicious of a bank transaction with an alleged Olympic Park construction contractor.

Police discovered the bank account set up to take $3.7 million from the authority was owned by a third fraudster. They believe the group was seeking to launder the money through Nigeria. Most of the funds were recovered.

Last year the third man involved in the scam, Ansumara Kamara, was jailed on similar charges.
