Hi there, we are going through a really bad time as a family. Had a false allegation made against the father in the family (was a teacher and revenge from student) we were under social services from Feb 2020 - case was closed in May 2020. Police were reviewing devices. In Feb 2021 they have deemed 6 photos on one of the devices indecent images (these were of the children at bath time). Solicitor is supportive of this being bath time photos. In the mean time the father is being kept away from home and not allowed any contact with the children until social services complete assessments. The children are safe, from a loving family, always been kept out of harms way etc. Obviously social need to look at worst case as we understand there are monsters out there. Yesterday social services met with the children and have them pieces of paper to draw a house with worry’s / wishes and their likes. One of our sons noticed in the top of each picture was typed text that said - the father of the children (name) has been arrested for sexual behaviour with children. Our son asked does this mean daddy is in jail?
Our question is - this is absolute incompetence of social services and is there anything we can do about this? Social services are there for the protection of children yet this failing has led to three very worried children who haven’t heard from their dad for weeks, they are terrified and now they have been handed this written statement from the social worker. The social worker apologised and said they weren’t meant to read this - but the damage is done. They won’t let their dad (who has done nothing wrong) telephone them - yet they put them at worry/anxiety and have given them nightmares. Affecting the children’s mental health. What can we do about this? Will this help us? This intervention has done nothing but affect the welfare of our children and not protect them.
