Mom was scammed 200k - can anything be done?

My mother, over the course of a year, was tricked into "investing" into a lucrative investment in Asia. She put 100k of her own money, and got 100k in lines of credit. the interest rate on the line of credit has finally cracked her and she finally informed the family she is in trouble. RCMP has been involved, and we also notified HKPD about the scam. Is there anything we can do to pause the interest on the LOC with the local banks?
