Shocking video shows a violent brawl between Chipotle workers and a customer in Connecticut, triggering a police investigation.

The melee occurred at the fast-casual chain’s New Britain Avenue location in West Hartford on Saturday, WFSB reported.

The startling footage appears to show a customer at the register throwing an unknown object at an employee, sparking a fight that spread to multiple individuals behind the counter as other patrons looked on in horror.

The Chipotle worker then appears to retaliate by picking up an item from the counter and attempting to throw it at the unruly customer, but is blocked — prompting other workers to rush in to help.

The violent customer then gets behind the counter, shoving workers out of the way and pushing the employee to the floor.

At the same time, a fight breaks out between the customer’s female companion and a female Chipotle worker, who begin trading blows as another employee attempts to break up the chaos.

Meanwhile, the female customer stands over a worker behind the counter as another employee tries to intervene.

The clip ends with the women pulling each other’s hair.

It’s unclear what sparked the violent altercation.

The West Hartford Police Department said it is investigating the shocking incident, but no arrests have been made so far.
