Tommy Lee is planning on pressing charges.
A Los Angeles County Sheriff's Department officer tells ET that police responded to the 55-year-old Mötley Crüe drummer's Calabasas, California, home on Monday night, where he alleged that his 21-year-old son, Brandon Lee, hit him. The officer also shared that Tommy was then transported to a local hospital.
The officer notes that when police arrived, Tommy had a visible injury on his face. ET has learned that nobody was taken into custody, but according to police, Tommy stated that he plans on pressing charges.
Brandon is the son of Tommy and his ex-wife, Pamela Anderson. The two also have a 20-year-old son, Dylan.
After Tommy tweeted out alleging his oldest son had assaulted him on Tuesday, ET reached out to Tommy's manager, Anderson's rep and Brandon's publicist.
In the 911 call obtained by ET, Tommy's fiancee, Vine star Brittany Furlan, told the operator that he was unconscious and alleged that Brandon had guns in his room.
"My stepson has guns in his room, and that's why I'm freaked out," Furlan claimed. "I just locked the door."
"In his mouth, he's bleeding," Furlan said, noting that she was having trouble turning him over onto his side, which the operator directed her to do. "I'm trying to, he's knocked out. He's unconscious."
However, at about four minutes into the call, Furlan told the operator that Tommy had started to come to. Another voice can be heard on her end of the line, and, while it's unclear who is talking or what is being said, Furlan indicated that Tommy had asked her to cancel the call.
"He's saying he wants me to cancel you guys," she said.
"He doesn't want you guys to come now," she continued. The operator told Furlan that they would still come to the house to make sure Tommy was OK. "Can you just cancel it? He doesn't want you here, and now he's OK," Furlan added at the end of the call.
Furlan claimed in the call that the argument started over a disagreement involving Anderson. When Tommy told his son to leave, she alleges that Brandon punched him in the face.
"He punched him really hard," she claimed. "He punched him in the face, and he went flying backwards."
On Monday night, when the incident allegedly took place, Brandon shared a few cryptic videos to his Instagram Story, saying, "As I get older, I have started to realize there are very few people you can trust. But anyway that's my super depressing thought for tonight, just thought I'd share it... be a d**k."
The following day, Tommy shared a since-deleted photo of his bloodied face via Instagram, with a caption that read, "My heart is broken. You can give your kids everything they could ever want in their entire lives and they can still turn against you. Good job Brandon! Great son!"
Earlier that same day, Tommy also posted an Instagram Story video, showing what looks like his son's messy room. "For all you girls potentially trying to date my son, here's what you get to f**kin' deal with," he said in the clip. It's unclear whether the room shown in the video is Brandon's.
Additionally, Furlan updated her Instagram Story on Monday with the message, "Violence is never the answer."
