hi,
emmz im glad the answer has helped. your reply has confused me a little. its difficult to get your head round all this police / legal business if your not used to it so never mind your not on your own.
if you were arrested and interviewed you would have been booked into custody. the arresting officer would have taken you into a custody office were your details would have been recorded and your property taken from you whilst in the station. you would have also been asked questions about your health, free legal advice and been asked to sign a document several times. you would have also been required to give (or withold) consent to having your fingerprints, photograph and dna sample taken. if this happen to you you were arrested.
if it did not you may have just had the caution given to you (as previously explained) and then had your account recorded on tape. this is an unfamilar practise to me but it very much depends on which police force you dealt with.
thanks.
