Octomom Under Investigation For Child Neglect

Octomom's hairstylist went to the PD today and she tells us ... she told cops she has been in the house and seen the following:

-- the plumbing is a disaster ... there is only one working toilet in the house
-- some of the kids are pooping on portable training toilets located in their bedrooms and in the backyard
-- the kids appear malnourished and unbathed
-- she observed Octomom locking her kids in a bedroom while she tended to personal matters
-- the house is filthy

The stylist made other allegations as well.

When the cop and 3 children's services workers arrived and walked inside, you can hear Octo say, "Excuse the graffiti."

The authorities stayed an hour-and-a-half and left. We're told they determined the kids not in danger so they were not removed from the home, but there will be follow-up with Children's Services.
