Three people are in custody after being arrested at the Blue Water Bridge in Point Edward Sunday night.
Lambton OPP were called by Canadian Border Services at around 11:30pm June 18 after a group of travelers were directed to secondary.
The trio was allegedly in possession of stolen property, as well as materials and tools used in the production of fraudulent credit cards.
The Lambton Crime Unit was called in, as police say it appears to be a very complex investigation, likely over several jurisdictions.
Lambton OPP say no further information will be released at this time.
