London teacher's murder reignites outcry over violence against women in the U.K.

London — The murder of a 28-year-old London elementary school teacher has reignited outrage over the prevalence of violence against women in the U.K., and fueled a debate playing out on both sides of the Atlantic over how much attention crimes get in the media depending on the race of the victim.

London police investigating the killing of Sabina Nessa made an arrest on Thursday, but on Friday evening they said he had been released, pending an investigation. No other suspects were in custody as of Friday, so the killer or killers remained at large.

Police say Nessa was making a five-minute walk from her home to a nearby bar to meet a friend when she was attacked. Her body was discovered the next day.
