Officers from the L.A. County Sheriff's Department arrived at Lindsay Lohan's apartment this afternoon to check on her little sister Ali Lohan's welfare.
Accompanying the deputies? Their father, Michael Lohan!
M-Lo went to the Sheriff's Department and said 16-year-old Ali Lohan was staying with Lindsay and that being said, he was concerned for her safety.
He convinced deputies to make a "welfare check" on Ali. Lindsay Tweeted that she's pissed at building management for letting cops and Michael in.
Sources say Ali was in the apartment and deputies spoke with her before leaving and allowing the teen to remain with her older train wreck sister.
Not to be deterred, Michael is now going to the L.A. County Department of Children and Family Services, per advice from the Sheriff's Department.

Michael made a "compelling case" to Sheriff's deputies, saying Ali was in Lindsay's car on the way back from Coachella and the car was going over 100 mph.
Not everyone is moved by his efforts, however. The girls' mom and Lindsay's chief enabler, Dina, wants Lindsay to get a restraining order against Michael.
With the legitimacy of the Sheriff's Dept. backing him this time, it's unlikely it would stick. Still, Dina Lohan vows that "My ex could be in big trouble. He's dangerous."
"If he can't get to them he is going to try to hurt them. It's not good."
Speaking with celeb gossip outlet TMZ after the incident, Michael steadfastly vowed to stay the course until Lindsay checks into rehab for substance abuse.
Michael says he will not leave L.A. "until Ali is removed from Lindsay's home and has a normal life of a 16-year-old. Anywhere Lindsay goes, I'm bringing cops."
The plot thickens! Should Linds heed her concerned dad's warnings and get help, or should that jerk just butt out? Whose side are you on?
