A small quantity of confectionery was allegedly taken.
Shortly before 4am today, a vehicle was used to gain entry into the same dairy.
Police eventually tracked down the vehicle allegedly involved and arrested two occupants.
The pair were youths and burglary charges are being considered, the police spokeswoman said.
Peace Street Dairy owner Kapita Khitri said the whole ordeal was "very sad".
"We are a bit shaken but getting there."
She said the fog cannon was activated during the first incident.
She said the ram raid this morning was the first in their 15 years owning the store.
