His comments come after Ziering, 59, updated fans on his condition after he and his 12-year-old daughter were "aggressively" attacked by bikers.

"I experienced an alarming incident involving a group of individuals on mini bikes. While stuck in traffic, my car was approached aggressively by one of these riders leading to an unsettling confrontation," Ziering shared on Instagram. "In an attempt to assess any damage I exited my car. This action, unfortunately, escalated into a physical altercation, which I navigated to protect myself.

Although the actor said he and his daughter were both left "completely unscathed," he addressed his concerns about "the growing boldness of such groups who disrupt public safety and peace." TMZ obtained video of the incident.

The father of two pointed out that he finds the traumatizing incident "unacceptable" and called on law enforcement to take action immediately.

"I urge city officials and law enforcement to take decisive action against such lawlessness and provide the necessary resources to prevent future occurrences," he said in part.
