Fraud and other charges were lodged this week against owners of a Niagara Falls, Ont. auto and marine repair shop, Niagara Regional Police reported.

Police launched an investigation on the Ort Road business last month and found that they had been called numerous times to the repair shop dating back to January 2010 for disputes between the operators and customers who dropped off equipment.

Police said some of the customers were told if they failed to pay what were inflated amounts of money, their property would be kept and subject to sale without their permission. Investigators corroborated the allegations and charged Shawn Ott, 43, and Stephany Steinhoff, 43, on Saturday.

Ott and Steinhoff were charged with four counts of fraud under $5,000, three counts of fraud over $5,000, two counts each of unauthorized possession and careless storage of a firearm, along with one count each of careless storage of a firearm and theft over and under $5,000.

Detectives continue to investigate the business practices of the operators of this repair shop, according to police. Anyone with information is asked to contact authorities in Niagara Falls at (905) 688-4111, Ext. 2200.
