Certainly sounds like an honor killing, as reported in Breitbart News:
"Six men have been arrested over the killing of a woman who was found dying in a London street with one of her hands cut off."
"The victim's estranged husband is among those arrested."
"Mother-of-two Geeta Aulakh, 28, was attacked in Greenford, northwest London, on Tuesday as she made her way to her childminder's home. "
"She was found with head injuries and a severed hand, according to witnesses. "
This looks like a Sikh honor killing:
"A friend said: 'It's horrific but hugely symbolic that Geeta's right hand was cut off. She was a Sikh and all Sikhs wear a metal bangle, the kara, on their right wrist. It is a permanent reminder to live a moral and good life and once it's on you can't get it off. So her murderer was both dishonouring her and perhaps tryingto show she had been dishonourable - which is just barbaric.' "
