“We have seized Samantha’s blue Peugeot 307 Estate car and are still keen to speak with anyone who saw her car with the registration HV04 ZFM being driven between 3pm on Wednesday 21 January and 5pm on Friday 23 January.
“I am also urging anyone who saw Samantha after 3pm on Wednesday, had contact with her whether by phone or social media or has any information about her movements, to call me in confidence.”
