Three accounts of assault and two accounts of racial discrimination were upheld in relation to the company, although the majority of complaints against the company related to loss of property and lack of communication. The company received over 700 complaints from illegal immigrants held in G4S detention centres in the UK in 2010, including allegations of assault and racism. However, the corporation insists that the level of substantiated complaints has been extremely low and they are of a minor nature. G4S's controversies became known to the wider public following their handling of security for the 2012 Summer Olympics, but controversy extends to the 1990s, before the company was founded in its present form by the merger of Group 4 with Securicor. The company operates as a subsidiary of an American security services provider Allied Universal since April 2021. G4S describes itself as 'the world's leading provider of security solutions' and provides security services for over 40 embassies around the world, work as stewards at football stadiums and runs over six British prisons, operates prisoner tagging schemes, assists within the Government Communications Headquarters (GCHQ) in the United Kingdom, and provides administrative roles to the health and education sectors.
