I have heard the following sentence in the German TV series "How to Sell Drugs Online (Fast)":
- Schnapp ihn dir, Papa!
Context: a police officer has just received an anonymous tip about a drug dealer at his home and his daughter says the sentence above.
"Schnapp ihn, Papa" means "get/catch him, dad", but I don't understand what the dative pronoun "dir" expresses in this sentence. I would literally translate it to "Get/catch him for you, dad", but that sounds odd. Or is "sich schnappen" just a synonym of "schnappen" ?
