A man has been arrested on suspicion of fraud after allegations by Olympic Park Legacy Company (OPLC) chairwoman Baroness Ford that Tottenham spied on Olympics officials during their stadium bid. The suspect was being questioned on Tuesday afternoon as officers conducted a string of searches in Sussex, Sutton, south west London, and Westminster.
Spurs have strenuously denied putting officials under surveillance.
Detectives, who have been investigating the claims since August 2011, "following allegations by West Ham and the Olympic Park Legacy Company in respect of the unlawful obtaining of information", said the suspect was arrested at an address in Sussex.
He was taken into custody at a Sussex police station "where he remains", a spokesman said.
"As part of their inquiries, detectives have conducted searches at both a residential and business premises in Sussex, a second private address in Sutton, and a further business address in Westminster," police said.
"An amount of material was seized during the searches."
Scotland Yard's Economic and Specialist Crime Command is leading the investigation.
