Hi
You are applying for a secretarial role, which means that you will either be asked for a standard criminal record disclosure or an enhanced criminal records disclosure.
The disclosure system changed recently and this has meant that only the enhanced criminal record disclosure can find out if a peron has been barred from working with children from vulnerable adults. Therefore, in the light of the fact that you will not be working directly with these groups of people, you will however have access to them, which can justify the enhanced check.
I would have thought you would be subjected to the enhanced check, but you may be subjected to the standard check as this role is not as sensitive as a doctor or nurse for example.
If you are asked to fill in a standard disclosure check, and the information you have described above is the only thing on your record, it will come back clean.
If you have an enhanced criminal record check done, it MAY show up. It is not definate. Tne arrest may be disclosed as the discretion of the chief police officer at the concerned police force and whether he thinks the arrest is relevent to the job being applied for. This is what it comes down to, whether the cheif thinks what has happened is relevent to the CRB check.
There is no definate way of being sure that it will show up or it won't show up. But it MAY show on only on an enhanced CRB check. You will either be subjected to the standard or the enhanced, and I would guess the enhanced, because the job is in a hospital.
You may wish to disclose the incident to HR before the disclosure comes back if you are being screened by the enhanced CRB.
Hope that helps
