Luis Diaz came off the bench to salvage a point for Liverpool with a stoppage-time goal on an emotional Premier League return at Luton.
Diaz's father remains missing after his parents were kidnapped in Colombia, and the forward lifted his shirt to show a message of "freedom for papa" after heading in Harvey Elliott's cross five minutes into added time.
It was a poignant and remarkable conclusion to a contest in which Luton had appeared on course for a deserved first league win of the season at Kenilworth Road and a first victory over the Reds since February 1991.
