There is a website using domain name similar to my business domain, However, he is tricking people by have restaurant website and let people transfer money to him online. However, How could I know the domain owner to file a police report where he is filled a wrong info for Registrant contact as shown below: Registrant Contact Name: Verve US Organization: Verve US Street: 6100 Center Drive Suite 1190 City: Los Angeles State: CA Postal Code: 90045 Country: US Phone: +1.7574166575 Email: xxxx@dns-protect.net
If it is about a gTLD domain name (you do not say) you can report suspicion of wrong/invalid data in whois records at https://forms.icann.org/en/resources/compliance/complaints/whois/inaccuracy-form
The sponsoring registrar will then need to conduct a search with the registrant to make sure everything is legit.
There are only two outcomes, besides no change at all: either the whois record gets changed and fixed or the domain name gets deleted.
Now if you have questions about a website legitimacy in selling services or such, you may better approach a customer protection agency or organization depending on the country you are in, like the BBB.
If you have a dispute on the domain name itself as you believe you have rights on them, again if it is a gTLD, look here: https://www.icann.org/resources/pages/dndr-2012-02-25-en#udrp Do not attempt to go further in that procedure without some legal counsel.
You can instead also go the judiciary route (again: do not attempt without consulting some legal counsel or attorney specialized on these issues), which will often start by your counsel written a letter (both postal and email) to the owner's data as written in whois before attempting anything else. Proof of non-deliverability will often lead to domain deletion. But if the problem is on the website the given website could restart seconds later on another domain name.
So you first should be far more clear on what your are speaking about (the domain name or the website?), and what are your goals?
