Locklear was arrested on Sunday night for battery against a police officer and emergency personnel, law enforcement officials told Fox News.
Locklear had been arguing with family and friends and appeared "extremely intoxicated" when deputies arrived, he said. Locklear reportedly punched a responding deputy who was trying to separate her from members of her family, then reportedly kicked an EMT while being placed on a gurney. After being held in California's Ventura County main jail facility on $20,000 bail, she was released just after 9 a.m.
Earlier this month, Locklear was hospitalised for a psychiatric evaluation after a family member told police the actress was searching for a gun to shoot herself with, TMZ reported, but did not have access to a firearm.
At the time, she was said to be engaging in an argument with another person.
Sunday's arrest was the second time deputies went to Heather's home that day.
It is understood the victim of that matter was her boyfriend, former high school sweetheart Chris Heisser, who suffered an injury.
She was fined $900 (£678) and sentenced to three years' informal probation after pleading guilty to reckless driving. Locklear is known for appearing in several "80s and '90s TV shows, including "Dynasty", "T.J. Hooker" and "Melrose Place".
She has previously spoken about her struggles with addiction. "It breaks her daughter's heart that Heather has been in so much trouble recently, and Ava has been pleading with her mom to get help", a source close to Heather EXCLUSIVELY explained to HL before today's incident.
