Delgado, who joined the BWF Council in 2007 before being elected to his current role six years later, is reported to be involved in a money laundering case in the South American country.

On Sunday (May 28), a judge ordered that the 52-year-old businessman be placed in pre-trial detention for 18 months before the hearing into the case, according to The Star in Malaysia.

It allegedly evolves around a bribe worth $1.2 million (£929,000/€1.1 million) apparently offered to Jorge Acurio, former Regional Governor of Cusco.

It is said he was approached with the money by Brazilian construction firm Odebrecht to give them the contract to build a new road in Cusco.

The Brazilian construction company has been accused using bribery and corruption to secure around 100 projects in 12 countries, including some linked to last year's Olympic and Paralympic Games in Rio de Janeiro. 

Acurio would have allegedly used Delgado to help transfer the payments through offshore firm Wircel SA.

Delgado had attended the recent Sudirman Cup event in Gold Coast, but failed to show up at the BWF Annual General Meeting, held during the tournament.

When contacted by insidethegames, the BWF said they were aware of the matter and are following developments in the case.

"At this stage, there is no confirmation of any wrongdoing and very limited information is available," a BWF spokesperson said.

"Therefore, the BWF is unable to comment further on these matters at present."

During his playing career, Delgado won a combined 19 national singles and doubles titles in Peru.

On May 20, Delgado was re-elected unopposed to the role of Deputy President at the AGM.
