The net closes in..... upon itself.

The title sounds like something from a cheap crime novel. 
Perhaps I've been inspired by reading about Detective Bob who, accepting the gratitude of his Station colleagues, places behind bars the master criminal, Hasselblad the Bad.
The extra shows a young seagull who, not having properly understood the sign, nervously scans the sky. 
Thanks to BobsBlips for hosting the closed/surrounded themed wide wednesday.
