A policeman involved in the arrest of champion golfer Scottie Scheffler is accused of stealing $4,000 from a suspect.

Louisville Metro Police officer Javar Downs was arrested on Friday after the man complained his money was taken during a traffic stop.

Downs pulled the man over about 12.45am on Wednesday on Taylor Boulevard and allegedly found an envelope with $10,000 cash inside and seized it.

However, the envelope only had $6,000 inside when he turned it in to evidence, police alleged.

Scheffler was arrested and booked into jail after not pulling over while on his way into the club for his second round at the PGA Championship
