Police are urgently appealing for information to help trace a woman from Batley.
Jodie Hudson, 36, was last seen at her home in Batley at 7.20am on Wednesday.
She is described as white, 5ft 1in tall, slim with shoulder length auburn hair and blue eyes.
She has a tattoo of flowers on her lower back and a tattoo of small footprints on her right foot which go to the ankle.
She was last seen wearing a neon yellow top, three-quarter length black jogging bottoms and bright orange New Balance trainers.
Det Ch Insp Ian Scott, of the Homicide and Major Enquiry Team, said: “We are concerned for Jodie’s safety. It is out of character for her not to be in touch with her family and friends and it is possible she may have travelled anywhere across the country.
“I appeal to anyone who has seen or heard from her since Wednesday morning, or who may know where she is now to get in contact. I would equally appeal directly to Jodie to contact police to let us know that she is OK. Enquiries are ongoing.”
Anyone with any information is asked to call police via 101 quoting 1380 of July 6.
