A fourth man has been arrested for alleged spying between West Ham United and Tottenham Hotspur regarding the Olympic Stadium row.
A 45-year-old man was arrested this morning in South London by police, who seized material from a residential home believed to be occupied by the man in question.
Earlier this month private investigator Howard Hill, who was employed by Tottenham, was arrested for allegedly obtaining phone records from Hammers vice-chairman Karren Brady.
The controversy surrounding the Olympic Stadium began last year after the Championship side won their bid to use the ground.
Spurs have maintained their innocence by refuting any suggestions of partaking in illegal activity.
