The overzealous fan who slapped Justin Timberlake on a golf course was beyond drunk at the time of the incident, according to cops.
TMZ obtained the Douglas County Sheriff’s report which says Keith Weglin‘s BAC was 0.18% when he got to jail … more than twice the legal limit.
TMZ broke the story … Keith was nabbed by cops after striking Justin in the face at the American Century Celebrity Pro-Am in Lake Tahoe. He could have gotten off scot-free, but cops say he refused to leave the course … so, they arrested him for disorderly conduct.
One law enforcement source said Weglin talked himself right into jail. We’ve reached out to him, but no word back yet.
