A department store was shut down and its managers fined thousands of dirhams when a flash sale drew in crowds of shoppers.
Ajman Police blamed retailers for the incident and shared footage of hundreds of shoppers in tightly packed queues in the unidentified discount store.
The Crisis, Disasters and Emergency Team said it expected all businesses to adhere to measures in place to tackle the coronavirus pandemic.
It fined the store Dh5,000 and urged other retailers to act accordingly.
Earlier, Ajman's government banned public Ramadan tents as part of measures to stop the spread of the virus.
Instead, it will oversee a food campaign to deliver meals to lower-income workers and families.
