I am still trying to catch up and about 20 pages behind, so pardon if this was already cleared up.
Firstly, it seems that everyone assume here that alleged Putney police officer who called fellow WS member hed-ts, got somehow his/her phone number from twitter as that was hed-ts own innitial thought and assumption, just due to fact that post he made to police was made through twitter.
What we know -
Sunday March 7, our member hed_ts tweet on twitter to police with CCTV image of two people on Poynders Road/Kings Ave CCTV at 21:30 showing the two individuals, with the dog and/or shopping bag
On the same day Met police post about 21:30 CCTV sighting on their police website and confirms it as last sighting of Sarah but walking alone on the A205 Poynders Road and from there various news agencies spread that news over the next few days. -
CCTV confirms last known sighting of missing Sarah Everard
Monday afternoon March 8 - allegedly Putney police officer contact him/her by phone and asked perplexing questions about those TFL CCTV images. Police officer does not explain how he obtained this private phone number.
Monday afternoon - hed-ts makes a first post about it here and about strange call from Putney officer. Hed-ts questions how the police officer got his number and laughts that probably in some strange way perhaps from twitter -
UK - UK - Sarah Everard, 33, London - Clapham Common area, 3 March 2021 #2
I think we all forget that in this day and age you can find phone number and many other information from many other online footprints or even elsewhere, not just twitter,
if this tweet was made under his/her real name.
Tuesday March 9 - Met police officer arrested in Kent with regards to Sarah's disappearance. (Please notice police announcement never specified that police officer was from there or lived there, only that he was arrested there).
At this point all else is an assumption, even if Putney police officer/person who called him on Monday and police officer/person arrested on Tuesday could be the same person.
Let's see if media in near future will mention anything about Putney.
