Dunn Discusses Health Issues and Bail Conditions

After being granted bail, Dunn said he was in a hospital being treated for mental health issues and he may not be well enough to undergo a police interview. However, he is supposed to remain in the United Kingdom until August 16 to report at the police station.

My mental health was taken into question and I am likely unfit for interview and so my interview will probably be after bail if I am fit. Time will tell. I have my passport and have not been cautioned not to leave the uk.
