His wife, Ayesha, tweeted that her father was racially profiled, and nearly arrested by security officials at the game.
Reports indicate that NBA security was looking for another man, David Aminzadeh, who apparently has tried to use fake credentials to sneak into sporting events (one report said he was arrested last year at an NBA All-Star Game Slam Dunk contest.)
Curry's wife ended her tweet with an apology. It was apparently in reference to an earlier tweet where she said the NBA was "rigged" for money.
Steph Curry reportedly makes $11 million a year to play in the NBA.
Reports say the NBA briefed Steph Curry after the game about what had happened with his father-in-law.
Curry is quoted as saying his father-in-law was "kind of profiled."
He called it an "emotional and tough night all around."
"All in all, it's just a game," Curry is quoted as saying, "I hope everybody is alright."
