Gunshots reported in Socal In-N-Out that 20 to 30 people quarreled in the restaurant

You can find something on the In-N-Out's infamous “Secret” menu, but the front seats for massive quarrels aren't one of them.

But that's some of the customers at Murrieta In-nout Saturday night, when police said a huge battle broke out at a fast-food restaurant, with officials estimated 20 to 30 people participating in the melee.

The department announced in an Instagram post that everyone was dispersed when officials arrived at the restaurant located in the 39300 block of Avenida Acacias.

While it is not clear what prompted the fight, police said someone fired a shot at one point, but there was no indication that anyone was shot or any property was damaged.

Detectives have surveillance footage from the scene, but are not ready to release any details.

Murietta police are seeking public help for more information about the fight. Anyone with details about the battle can call investigators at 951-461-6353 or rleitch@murrietaca.gov.
