In the Feb. 26 incident, Locklear, 56, was arrested after she allegedly assaulted her boyfriend, Chris Heisser.
When police arrived, the actress became increasingly threatening and combative. She allegedly threatened to "shoot (police) if they ever came to her house again." Police later returned to her home with a search warrant to look for a firearm in her name, but it was not recovered. Locklear was not home at the time of the search.
TMZ reported that Locklear was not at home at the time of the search because she had checked herself into a treatment facility. The latest stint in rehab isn’t her first. She has sought treatment five previous times, including one stay last year.
The Associated Press reported that Locklear is scheduled for arraignment Tuesday in Ventura County Superior Court.
