Police are appealing for the public's help in tracing a missing mother and her child.
Charlotte Nash, 24, and Ethan Nash, 4, have been missing from their home in Whittlesey since Friday (January 25).
Despite numerous police enquiries officers have been unable to trace them.
Charlotte is described as white, around 5'4" with long dark hair. Ethan is described as white, with cropped dark brown hair and brown eyes. He wears glasses and has a squint in one eye.
"We are concerned for Charlotte and Ethan's welfare and would urge anyone who has any information about their whereabouts to contact police. I'd also like to appeal directly to Charlotte to get in touch with officers."
Police believe the pair are together and likely to be in the local area, either Whittlesey or Peterborough.
