Amy Barnbrook last spoke to a relative on June 26 but her mobile phone has been off since then.
Officers have visited her home and she hasn’t been there either. It is believed she is in her blue Honda Jazz with registration GU10 OSW.
She is 34 with shoulder length brown hair but it is not clear what she might be wearing.
Anyone who knows where she is or has seen her car, please get in contact online quoting serial 539 of 02/07.
