I have to echo the earlier comment re. the homeless man. Was he seen by the crisis team in A&E? In our area we will see anyone presenting with a mental health crisis although we do like the person to have been checked out by a doctor first of all to rule out any physical cause for their presentation. In the case of homeless people, we assess them in the local A&E dept. The person might be stating suicidal ideas for a variety of reasons but it is still best to assess them and, preferably somewhere safe and appropriate. As for hours of operation...we are a 24 hour service.
