History
It was formed on 11 March 1985 by Commissioner
Kenneth Newman. At its peak, Specialist Operations (SO) was a group of twenty specialist units, which were formed to give the Metropolitan Police a specialist policing capability. The SO designation was implemented in 1985 as part of
Sir Kenneth Newman's restructuring of the Metropolitan Police Service. Most of the units designated SO units were already in existence, many of them as branches within
C Department of New Scotland Yard, and all were presided over by an Assistant Commissioner of Special Operations (ACSO).
In 1999 its Organised Crime Group took over residual work from the disbanded
War Crimes Unit.
In 2010, ACSO co-directed
Operation Guava, aimed at "a significant terrorist plot". The aim of this ACSO action was to prevent the establishment of a jihadist training camp in Kashmir on land owned by one of the suspects. Operation Guava resulted in the 2012 conviction of
Usman Khan, who went on to perpetrate the
2019 London Bridge stabbing.
