Now how did they get in there?

All that nice new tiling at Arsenal too

Holloway Road and Caledonian Road had been completely cleaned by the
27th, Arsenal by the 29th - good work, TfL anti-graf squad. No visible
damage to the new (or old) tiles in any of the stations. Speedy removal
is the best defence.
