Checking records in the UAE before applying for a visa to Canada

Dear Sir,

Greetings of the day,

One of my friends who worked for a hotel in Dubai has taken AED 50 extra money from a guest and kept in his pocket, which has been identified by the management who cancelled his visa and sent him back to India.

Now, he would like to apply for a visa to Canada, so he is worried if there are any charges or cases imposed against him in the UAE which will not permit him to apply for the visa to Canada.

Please let me know how to check if any charges have been imposed against my friend.
