Police in Calderdale now believe a call made to the local NHS 111 number was a hoax.
Officers yesterday issued an appeal to trace a woman who gave her name as Sarah who had called the line at 4.22pm on Thursday, May 8.
She was in distress and alleging that she had been the victim of a crime and had taken a large amount of tablets.
Chief Inspector Viv Cutbill, of Calderdale Police, said: “The nature of the call raised genuine concerns for this woman’s safety and we conducted extensive enquiries to trace her. Our investigations now suggest that the call appears to have been a hoax. We are continuing to investigate the situation and will take appropriate action with regard to any offences.”
