Tony Imossi

In 1981 Tony Imossi established an agency to provide discreet, confidential investigation services to the legal profession, corporate businesses and individual professionals. The agency has since specialised in corporate fraud, theft, due diligence and general litigation support.


During a career spanning 15 years in the legal profession, Tony worked in a number of areas of litigation for London solicitors, whilst dedicating his spare time to the Parachute Regiment’s territorial unit, through which he was commissioned and attained the rank of Captain.


Tony joined the Association of British Investigators (ABI) in 1986 and was named Investigator of the Year in 1999.  In 2003 Tony was further acknowledged by the ABI when he was presented with the award for service to the industry, which he was awarded again in 2013.


Tony was President of the ABI from 2000 – 2004 and subsequently re-elected as President each year since 2008. During this time he has overseen radical improvement of the ABI’s membership criteria to levels not previously experienced in the UK sector. These high standards led to the unique accreditation of the ABI by the DVLA (2008), its endorsement by The Law Society of England & Wales (2010) and inclusion in The Law Society of Scotland’s Service Provider Scheme (2011).


Tony is the founder and former Chairman of the UK industry-wide ‘Investigators’ Sector Group’, which, from 2001 to 2008 spearheaded the consultation process on regulating the investigation sector and focused on de-fragmenting the UK and European-wide private investigation sector. In 2004, Tony was appointed Secretary General to the European umbrella body, Internationale Kommission der Detektiv-Verbande, which is currently working on its EU common minimum standard and good practice recommendations for investigations in the private sector.


During 2012 and 2013 Tony played a key role in drafting the British Standard Institution Code of Practice for the provision of investigative services (BS102000). In the absence of government licensing of the investigator market, this Standard ensures certified investigators are operating to the highest ethical standard. Following the Standard’s publication Tony was recognized as a leading industry expert and tasked to train the Security Industry Authority team and the SIA accredited Assessors on the BS102000 certification.


In 2004 the Joint Security Industry Council recognised Tony’s achievements with the award Gold Medal for Excellence. A similar award was granted to him in 2013 by the World Association of Detectives - acknowledging his world-wide contribution and professional leadership.


In February 2012 as part of the government sponsored inquiries and reviews, which covered regulating investigation in the private sector, Tony gave detailed written submissions followed by oral evidence to both the Judicial Inquiry chaired by Lord Justice Leveson and the House of Commons Home Affairs Select Committee chaired by The Right Honorable Keith Vaz MP.


Tony is qualified having obtained the Level 3 Award for Professional Investigation (QCF) and his business is certified to British Standard Institution BS102000 for the provision of investigative services.
