Riots stance on irl death threats.

Just want to know what Riot's stance on irl Death threats are. Do you report in the report tab after the game or do you Contact the player support directly? And yes, its an actuall dath threat directed at a team member of mine. ''F**K YOU I WILL FIND YOU AND F**KING MURDER YOU, I HOPE YOU DIE'' Soooooo, report tab, player support or both?
