The Midway Dairy in Milton has been broken into for the second time in three weeks.
The owners discovered the break-in at the Union St store on Friday morning.
A police spokeswoman said the owners found someone had tried to gain entry to the store and caused a pipe to burst.
One of the owners, who did not want to be identified, said it was the second break-in in three weeks.
''It's just shocking ... It's horrible.''
The wall was damaged and pipes were leaking when the break-in was discovered.
It was disappointing because they had updated their security since the first break-in, the owner said.
The police spokeswoman said police responded to a burglary at the store, in which cash was taken, after the night of May 28.
The White Horse Inn, in Milton, was also reported to have been burgled on June 6.
