Los Angeles police responded to an incident at Lee's home in Calabasas, California, on Monday nightm after an apparent altercation between father and son left he Mötley Crüe drummer with a bloody lip. Lee was taken to hospital shortly after.
Brandon, who was not at the scene when authorities arrived, has been named a person of interest in the ongoing investigation for criminal battery. So far no arrest has been made, and authorities say his attorneys are cooperating fully.
Law enforcement officials told PEOPLE that in the lead up to the alleged assault, the pair had been arguing about a series of tweets the 55-year-old musician had been posting responding to Anderson's interview on an episode of Piers Morgan's Life Stories . During the episode, which aired on Saturday night, the former Baywatch star discussed physical abuse she claimed to have endured from Lee during their relationship.
In 1998 Lee was sentenced to six months in jail for spousal battery following an assault that left Anderson with bruises and a torn fingernail. She was reportedly holding their infant son, Dylan, now 20, at the time.
'Think she’d find something new to discuss instead of rehashing old s— but I guess she has nothing else going on & needs attention Signed, ‘The abuser’ (who she texts every day & asks for me back),' Lee tweeted.
On Tuesday, after the alleged incident occurred, Lee tweeted: 'My heart is broken,' he captioned the image. '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!'
Meanwhile, Brandon responded on Instagram, saying: 'As I get older, I have started to realize that there are very few people you can trust…that’s my super depressing thought for tonight. Just thought I’d share it and be a d—'.
