Atascadero man with a BB gun prompts school lockdown

May 11, 2021


Local officials placed Atascadero Middle School on lockdown Monday afternoon after a man was walking nearby brandishing a BB gun that was initially thought to be a rifle.

Shortly before 2 p.m, a 911 caller reported a man with a rifle had entered the creek behind Atascadero Middle School. Officers arrived at the scene and were told the man had approached a resident on Capistrano Avenue while carrying a weapon that looked like a rife.

The suspect then fled toward the creek, according to the Atascadero Police Department.

Officials placed Atascadero Middle School, as well as the Atascadero Unified School District office, on lockdown due to their nearby locations.

Police established a perimeter and launched a search for the suspect. During the search, another 911 caller reported the man had brandished a rifle at children who were playing outside.

Shortly afterwards, officers located the suspect, Arthur Castellanos, 45. Castellanos admitted to having a BB gun rifle, according to the police department.

Officers found the BB gun at the scene. Investigators later determined Castellanos was the man who had brandished a weapon at residents.

Police arrested Castellanos and booked him in San Luis Obispo County Jail on charges of brandishing a firearm, violating probation and having an outstanding warrant. As of Tuesday morning, Castellanos is no longer in custody.


So to recap the suspect:

*Has an outstanding warrant

*Is currently out on probation

*Brandishing a weapon that can cause serious injury at school kids

And is immediately released back to the public as a direct result of the policies enacted by California’s elected officials. WTF is wrong with our political system and the people that vote them in office… Unbelievable.


I don’t like the crazies wandering our streets and living in the creeks but need to ask, was it a firearm? I believe that a BB gun is not.


A firearm is defined as ANY type of gun. You wanna get popped by one? Doubtful.


Even a super soaker?


Imitation firearm. Would not be surprised if this state soon requires a background check, 10 day waiting period, And maximum purchase of 50 bb or pellets.

I really cant believe I was allowed to purchase a bb gun at 8 years old. My parents and wamo should be charged with contributing to the delinquency of a minor. I’m so lucky the bb gun didnt decide to hurt me or others.
