After the video of her dancing with knives, police went to Britney Spears’ house

(CNN) –– Authorities responded to a call to go to Britney Spears’ home in Southern California on Wednesday to check if she was OK after the singer posted a video on her social media in which she was seen dancing with knives.

A person close to Spears who was “really concerned about her well-being” called authorities, Ventura County Sheriff’s Office Chief Dean Worthy told CNN.

“Some might say she (Spears) is simply expressing her creative freedom, others might argue that this is dangerous and that there is a safety or mental health issue,” Worthy said. However, based on the first call from a person close to Spears, authorities decided to check on the singer’s well-being.

CNN has reached out to a representative for the artist for comment.

The first call from the person close to Spears, whom authorities did not identify, was made to the Los Angeles Police Department’s mental health assessment team, which then forwarded the call to the sheriff’s office, Worthy said.

So the sheriff’s office sent a sergeant who “had several prior contacts with Ms. Spears over many years” and who also had a good relationship with the singer, Worthy said.

According to Worthy, the sergeant arrived at Spears’ home in Thousand Oaks, California, to inquire about her well-being and was contacted via a door phone by a member of the singer’s security team. The sergeant “stated that he came based on information.” [Spears] could be in a potential mental health crisis or at risk of self-harm,” Worthy said.

The singer’s head of security told the sergeant that he was with Spears, that there was no threat to her safety and that the artist did not want the agents on the property. Worthy added that Spears’ attorney also called the sergeant, “explained to him that he had just spoken to the singer” and “assured him that there were no mental, physical or other problems with Ms. Spears.”

On Monday, Spears shared a video on Instagram of herself dancing with what appeared to be two metal kitchen knives. She later updated the post with the caption, “Today I started playing with knives in the kitchen,” before adding, “Don’t worry, they are NOT real knives!!! Halloween is coming up soon!”

After receiving assurances from two independent parties that Spears was not in danger, Worthy said the sergeant left the residence.

In January, Spears was subjected to another welfare check when she said “prank calls” prompted police to visit her home.

The singer posted a note on Twitter at the time about the police visit, saying: “I love and adore my fans, but this time things went too far and my privacy was violated.”

Spears went on to say that police “never entered” her home and that when they arrived, she “quickly realized there was no problem and left immediately.”

The singer complained that the incident had left her feeling “agitated and intimidated” and that “the media had once again portrayed her poorly and unfairly.”

“At this time in my life, I truly hope that the public and my fans, whom I love so much, can respect my privacy in the future,” she wrote.

In an email to CNN in January, Sergeant Jason Karol of the Ventura County Sheriff’s Office confirmed that the department had “received a few calls from concerned fans” after Spears deleted her Instagram account.
