A Sherriff’s Office in Monterey Bay, California has issued a warning to the public, after a cosplay photoshoot held on a public beach raised concerns due to those involved using a large rifle.

Locals alerted the authorities after becoming worried about the intentions of those in possession of the firearm. As per KRON4, the incident occurred at Seacliff State Beach on July 3rd. Now, pictures from those who were at the scene clearly show both the photographer and model walking along the beach, with the latter carrying the huge rifle on her arm, seemingly unaware of any panic they may cause to onlookers.

Since the images emerged, the Santa Cruz Sheriff’s Office has publicly reiterated the seriousness of such actions. Sgt. Dee Baldwin said in a statement:

As we’ve seen in the picture they’re walking around having a good time with what they know may be a fake firearm, but our responding officers don’t have any idea what they’re walking into.

The state of California does not allow you to “openly display or expose any imitation firearm in a ‘public place'” unless said firearm is “entirely transparent” or covered in “certain bright colors.”
