There is no way British intelligence could have acted so quick, if it was true. Maybe if he/they were already being watched.

This is an interesting theory, if it's technically possible would be it. For sure airports would watch such traffic if they technically can.

The WiFi network in one of the London airports had this weird phone time error when connecting, it wanted to update time definitions, I always wondered if it's had to do with certificate validation, or just a simple misconfiguration, or even if it was just my personal device.

or maybe, hear me out, there was a person sitting next to him at the airport and saw his snapchat messages and freaked out?
