Thank you Terence for drawing this to our attention.
The message was put out in good faith by one of our neighbourhood teams. As you rightly point out, this is an old hoax, and it is disappointing that the officers did not carry spot that (a quick internet search would have sufficed) before sending it on.
The Sergeant for the team has been informed and will be speaking to his officers.
We will also be emailing all staff to remind them to check information of this kind before passing it on to the public.
