Freedom of Information request – FOI/2024/01244

Annex B

You asked for the following:

1. How are small boats and migrants detected, and by whom?
2. What technological means and methods are employed for detection?
3. How is detection data processed? And a clarification, equally numbered 1. And 2.

Response

I confirm that the Home Office holds the information that you seek. However, we have concluded that such information would be exempt from disclosure under Section 31(1)(a), (b) and (e) of the FOIA, as release of this information could prejudice the detection or prevention of crime, the apprehension or prosecution of offenders, and the operation of the
immigration controls.

Section 31 of the FOIA is a qualified exemption and requires consideration of the public interest test. We have concluded the public interest lies in favour of withholding the information. Arguments for and against disclosure in terms of public interest, with the reasons for our conclusion, are set out in Annex C.
