A 54-year-old Simi Valley man is behind bars after police say he used a box cutter to slash another man's face during a confrontation before sunrise on Saturday. The attack happened in the 2700 block of Tapo Canyon Road and left the victim with a serious but non-life-threatening injury, according to a police news release.
The incident was reported around 2:50 a.m., according to the news release, as Ventura County Star reports. Officers arrested the suspect on suspicion of using the sharp-edged tool to slash the victim's face, per the same account. No further details about the circumstances leading up to the attack, the identities of those involved, or any possible charges have been released.
California law does not treat a box cutter as automatically deadly just because of its design. In a 2019 case involving a box cutter, the California Supreme Court said it is not inherently deadly; whether it qualifies as a deadly weapon depends on how it was used. The ruling makes the alleged use in this case legally significant, but it does not establish what happened here or indicate what charges prosecutors may file.
A Weapon With a Troubling History in Simi Valley
This isn't the first time a box cutter has turned up as a weapon in a Simi Valley assault. In May 2024, a 36-year-old Simi Valley man was struck in the head with a box cutter and taken to a hospital after a fight broke out at a party in the 4700 block of Adam Road, according to vcstar.com. That victim suffered a laceration over his left eyebrow, and police did not believe his injury was life-threatening at the time.
The suspect in that earlier case, a 35-year-old Simi Valley man, was arrested on suspicion of assault with a deadly weapon and later released, the outlet's report noted.
If prosecutors file an assault-with-a-deadly-weapon charge, California Penal Code section 245(a)(1) allows a sentence of two, three or four years in state prison, or up to a year in county jail, and provides for a possible fine. The statute sets those penalties, but the arrest described by police is not itself a conviction—and the information released so far does not say that this charge has been filed.
Other Recent Weapon Violence Outside Simi Valley Bars
Knives and sharp objects have surfaced in other Simi Valley altercations as well. In July 2024, a dispute inside a Simi Valley bar spilled into the parking lot, leaving two people stabbed and resulting in four arrests, the outlet reported. A 31-year-old man was arrested on suspicion of at least assault with a deadly weapon in connection with that fight.
As with the Adam Road case, nothing in the available reporting ties that bar-area stabbing to the Tapo Canyon Road incident reported Saturday morning. The current case remains under investigation, and no additional information about a court outcome or case status has been released.
