A knife-wielding maniac was caught on terrifying doorbell camera footage repeatedly making stabbing motions outside stunned Sacramento-area homeowners’ front doors — sending an Arden neighborhood into panic as the suspect remains on the loose.

Rebecca Breen and her husband were watching TV around 8:30 p.m. Thursday when their Ring camera suddenly began sending alerts that someone was at their front door, KCRA reported.  

“We started getting alerts on our phone that there was action on our motion on our Ring camera at the front door,” Breen told the outlet.

Moments later, the couple heard pounding.

“We heard a loud knock and we looked in the ring camera and we noticed that there was something very strange going on,” she said.

The chilling footage showed a man brandishing a knife while appearing to repeatedly stab toward the home’s entrance.

“It was terrifying. It was absolutely terrifying,” Breen added.

She immediately dialed 911.

Sacramento County Sheriff’s Lt. Amar Gandhi said multiple frantic residents reported the armed prowler as deputies rushed to the scene within minutes.

“There were several residents calling, stuff is actually caught on Ring camera. So our deputies got there, got in the area actually, just within minutes. But by then he’d fled,” Gandhi said.

The sheriff’s office also deployed a helicopter in the search, but the suspect vanished before authorities could catch him.

“It’s pretty scary stuff. He’s going out there literally thrashing on doors with knives. But fortunately, again, nobody hurt. People were very smart in the sense of lock the doors, stayed inside and called us,” explained Gandhi.

Breen doesn’t believe her family was specifically targeted.

“I do believe that we were a random target. I don’t think that we were specifically targeted, but I think it’s very scary because if it wasn’t us, it’s going to be someone else,” she said. “I mean, clearly he was not in his right frame of mind at all.”

Neighbors reported that private security never showed up, and several residents expressed frustration at how long it took law enforcement to reach out to homeowners after the frightening ordeal.

Deputies are still searching for the suspect.
