Some weeks back I made an obscure comment (in the panic thread) relating to the subject below. I'm pleased it has now broke into the public domain.
Can you imaging how many people are working in law enforcement and being told not to download the app? How will this help track and trace, well I can't see it helping one bit. Making the whole scheme significantly less effective.

The National Police Chiefs Council (NPCC) has confirmed officers are being told not to install the NHS Covid-19 app on their work smartphones.
The app detects when users have been in proximity to someone with the virus.
Some officers have also been told they may not need to obey self-isolate alerts generated by the app when downloaded to their personal phones.
Lancashire Constabulary has told staff to call the force's own Covid-19 helpline instead.
The BBC contacted the North-West of England force after a source claimed the advice had been given because of "security reasons".
The source also said officers had been told not to carry their personal phones while on duty if they had activated the app.
This applies to staff working in public-facing roles as well as those in back-office positions.
"The health and wellbeing of our officers, staff and the public remains our priority," a Lancashire Constabulary spokeswoman subsequently told the BBC.
"Members of staff, like all members of the public, are personally able to download the Track and Trace application should they choose to do so. Guidance provided to staff within the workplace remains in line with the national NPCC position."
The NPCC confirmed the work-phones policy was common to all forces, and said it was carrying out an urgent review of the matter.
"Police forces use a variety of mobile devices with different system restrictions," said a spokesman for the council.
"It is important that we have confidence that the NHS app will work for officers and staff consistently across the country, and it is for this reason that we have recommended that officers and staff download the app to their personal, as opposed to work devices, rather than any suggestion of security implications."
@Dame_Ann_Average - I bet you knew already 
CID
I understand why they are doing it, mainly it's because they don't want hundreds of staff off, which could lead to a breakdown in the police being able to, well, police. However, it does not help reduce and detect the spread of C-19.
Thought we might have had you join us in the Cop thread at 9 EC ....new series of programmes about catching the criminals on C5
