18 years ago the police covering the area in which I worked had an agreed policy with area social work teams, that a written report of every incident the police were called to, where domestic abuse/violence had occurred, and where there were children in the family.
As night owl says, there were too many for every one to be responded to with a social work visit. The exception would be families where we already were involved, or had previous involvement. Or if the incident had involved extreme violence.
Our team wrote to every mother, informing her we were aware of the incident, and offering support if she wanted it. We enclosed a list of agencies that could offer support to men, women or children. A 2nd police report always resulted in a letter arranging a social work visit. Our aim was to support the victim, usually the mother and always the children. Of course, we weren't always welcome, but we ensured the parents were aware of the damage caused to children growing up with domestic abuse. Three incidents, and non co-operation would result in a multi agency meeting.
Nightowl's comments about 'safeguarding' being everyone's business and responsibility are spot on. I've recent knowledge of unqualified family support workers being asked to be 'lead professional', or to undertake the Children and Family Assessment. Everyone involved has a significant role, but their knowledge base is different. Only qualified, well supervised social workers, with regular training inputs should be completing investigations where children are suspected of being at risk. The power lies with the social workers, they're the only people who can initiate court proceedings, and that has to underpin work with individuals like Hamzah's parents. That power needs to be exercised sensitively, supportively and in a child centred way.
Aka - I fully accept your points about Hamzah's father's comments. They should have been properly investigated. I've read there were 2 multi agency meetings - how can they have happened without prior investigation by a social worker, whose responsibility includes speaking to everyone with first hand knowledge of the children. That should include family members, parents, school and health. I also agree with nigh owl, that we need more health visitors. Failure to attend clinic, immunisations or see the GP in a family like this should have been ringing alarm bells very loudly. As others have said, it doesn't seem possible that the care given to the older children didn't raise concerns in schools. Like everyone else on this thread, I'm shocked and distressed at the failure of anyone to intervene effectively.
