The Winona County Sheriff's Department is investigating the second break-in in a week at Johnny's Saloon in Elba.
Chief Deputy Ron Ganrude said entry on Saturday was gained through a window and $20 in cash from a tip jar was discovered missing. A cash machine was also attempted to be opened but unsuccessfully.
The bar had been entered sometime between 1:15 a.m. and 6:30 a.m. Saturday.
Authorities are continuing to investigate the first burglary that occurred a week earlier on May 25th.
