A woman was treated in hospital after apparently being injected in the arm by a woman who asked her for money in a Manchester shopping area.
The offender grabbed hold of her arm in King Street
The 32-year-old victim was walking on King Street at about 1800 GMT on Friday when she was approached by a woman.
She gave her some change but the offender then grabbed her arm and scratched it with an unknown implement.
The woman immediately felt unwell and was taken to Fairfield Hospital for treatment, but was later discharged.
Police are urging people to be on their guard when approached by strangers wanting money.
Anyone with information is urged to contact police or Crimestoppers.
