The information requested is not held centrally. The police use their powers at an airport in the same way as at any other location as appropriate. Information held by the Ministry of Justice on the number of arrests is based on aggregated data reported by the 43 police forces in England and Wales. Data are collected centrally by main offence group such as violence against the person, sexual offences, drugs offences, etc. It is not possible to determine from these data the circumstances or location of an arrest, such as an airport.
