Yes we did in the end thanks bright. A heartfelt plea and a bit of background explaining to police fom us, plus GP from 111 (with access to notes) recommending the police act helped somewhat. Was not easy, I had to persuade her over the phone to go with the police to a MH ward, which thankfully she did, where they soon took action to section her to prevent her from leaving. She is already responding well to treatment and the ward staff have been wonderful.
Staggered and angered by lack of out of hours availability of social workers and care team though - you used to at least be able to speak to a duty social worker out of hours, not anymore.
It's so sad to think we so very nearly lost her to the streets. It shouldn't be so hard to get a person to hospital when they are clearly unwell, and not able to look after themselves.
