The integrity division of sports betting consultancy Starlizard, Starlizard Integrity Services (SIS), has revealed it has detected suspicious activity at 84 football matches.
The matches were held in a range of leagues across the world between 1 January and 30 June, with 31% of them taking place in the top league of each match's particular country.
SIS analysed 18,845 matches during this period, with the flagged matches representing 0.45% of this sample size.
Data from SIS marked 84 matches as suspicious, which is defined as a match that has suspect betting patterns associated with it, a possible indication of match-fixing.
