I was at Luton Airport last Sunday on a domestic flight.

After passing through the security checkpoint, there are a number of "Police Control" desks. These are usually unmanned at all UK airports. Unusually, there were two Border Force officers stopping random passengers.

Whilst questioning passengers, both officers appeared to be spending a long time looking through a mobile phone - not sure whether this was the passenger's phone or some other device. The stop appeared to go on for a while (i.e. longer than just to check a passport).

I observed all of this whilst at the water fountain after security, so didn't hear any of the conversation.

Has anyone seen this going on before in the UK? I know Border Force can randomly stop people (for up to 9 hours) under Schedule 7.
