Thieves are using dating sites to steal cars, with police saying victims are often too embarrassed to come forward.

The cold hearted schemes are becoming increasingly common.

Thieves get in touch with their victims via online dating websites and arrange to meet in the victim’s home before taking their car keys.

Images have been released of a suspect involved in one such incident that happened in Langwarrin on January 3.

That car later used in a liquor store robbery.

Detective Leading Senior Constable Richard Thomsons believes dating website linked car thefts may be under-reported, telling the Herald Sun victims were often too embarrassed to come forward.
