De-arrest statistics

Dear Sir or Madam,

I have noticed a number of reports in the press regarding people
being arrested and then later de-arrested.

In some of these cases the impression given is that the police are
using arrest/de-arrest as a 'convenient' and simple way of
temporarily removing people from a location and detaining them for
a time with out genuine due cause.

I would like details of de-arrests nationally over the past (say)
year, showing the time, police officer, geographic location and
reason for the original arrest and the time, location and
justification of the de-arrest. Can you tell me what information
you hold that could assist me with this?

Also any information that you have collated yourselves regarding
the use of de-arrests.

Yours faithfully,

Paul Perrin

Dear Mr Sharp,

I am rather surprised that there is no oversight of de-arrests, as
it would seem that my initial concern (that it appears that this
may be being abused) could well be true, and no one would be aware
of the fact.

However thank you for your response.

Yours sincerely,

Paul Perrin
