Arrest Records Retention times

Dear Sir or Madam,

I wish to know how long Strathclyde Police hold arrest records on
people who have never been convicted of ANY offence for the
following;

1: Drink Driving
2: Breach of the Peace
3: A Serious Assault

Yours faithfully,

John Anderson

Dear Colette McFarlane,

Thank you for your quick reply.

As requested . if i may clarify.

I wish to know when a person is arrested their name, address, date
of birth, occupation, photograph and presumably the alleged offence
is recorded on the Police computer system somehow. This is which i
refer to as an arrest record. I wish to know wow long Strathclyde
Police retain this information for when a person was not convicted
of any offence.

Yours sincerely,

John Anderson
