I don't quite get when "persons" can be used and when "people" is appropriate. Could you explain a little bit?

You can think of "persons" as being similar in meaning to "individuals." It's a more formal, archaic way of saying the plural form of "person." "People" is used more often when you are referring to a collective group or indeterminate/unspecified number. However, this difference is not very important as both "persons" and "people" are plural nouns for "person." The speaker could have used "people" here and it would have been absolutely fine. So don't worry about this difference too much, as "persons" is not very commonly used! Ex: There are two persons under investigation. (Individuals) Ex: There are two people under investigation.
