7:20 AM PT -- Law enforcement sources tell TMZ ... Sunday's arrest was the second time deputies went to Heather's home that day. We're told they were there around 6 PM for another disturbance, but determined no crime had occurred.
Heather Locklear was arrested Sunday night for battery on a police officer ... and this is the second time.
Locklear was taken into custody at her home shortly before midnight and booked for 2 counts of misdemeanor battery upon an officer and emergency personnel.
The original 911 call was for a disturbance. Law enforcement sources say she was heavily intoxicated when a family member called. Heather, who we're told was extremely agitated, punched a responding deputy who was trying to separate Heather from members of her family.
Paramedics arrived and, while putting her on the gurney, she kicked an EMT.
Heather was taken to a hospital to get checked out and then was taken to jail where she was booked. She's being held on $20,000 bail.
Locklear was placed on an involuntary psychiatric hold last week after allegedly choking her mom and attacking her dad.
