Belle -- a 5-time All-Star during his 12-year MLB career -- was arrested in Scottsdale and booked into Maricopa County Jail.

The ex-slugger was arrested for 2 counts of indecent exposure and 2 DUI counts.

The 51-year-old is listed as 6'2", 270 lbs in the jail database.

This isn't the first time Belle -- who was one of the most feared hitters in the game -- has been in trouble with the law.

He spent time in jail back in '06 after pleading guilty to stalking his ex-girlfriend.
