We shouldn't forget that in the UK, two women are killed every week by their partner/ex partner. (government figures 2017). The time they're most at risk is when they leave. That's one of the reasons so many women remain in abusive relationships. Their partner tells them if they do leave, they'll be hunted down and killed. Levels of violence and emotional control these women have experienced over long periods has them believing the threats (with good reason)
This woman was living in a safe house, which suggests the police and other agencies considered her to be in a very high risk category. The news today reports that the attack was carried out my men from the Roma community. The suggestion is that the father/ex partner discovered where the family were hiding after a photograph of one of his children at a school appeared in a news paper . He then paid the men to carry out an acid attack on his ex partner, the attack went wrong and the child was injured.
Its horrific, anyone who has worked with victims of domestic abuse will know of similarly dreadful situations. Let's hope this woman and her children can be safely re-housed, try once again to rebuild their lives and achieve a degree of calm.
