A 42-second video posted on Facebook and first reported by RLS Media shows the Feb. 5 incident at the downtown Newark restaurant. A man and a young child walk into the restaurant, and the child is eager to touch the rodent, which is contained in a clear, plastic case.

The man walks to the middle of the restaurant and releases the rat, causing customers to scream and scramble out of their seats, NJ.com reported.

There were no injuries reported, RLS Media reported.

Celest Quintana, the owner of the McDonald's franchise, said in a statement to NJ101.5 "The safety of our customers and the cleanliness of our restaurants are our top priorities.

"We are currently working with local law enforcement to identify the person responsible for this deliberate act.”

No arrests have been made, but a Newark police spokeswoman told NJ.com the department is investigating.
