Kobe Bryant's 19-year-old daughter is scared, and so is the LAPD ... they say a stalker with a criminal history involving guns has been doing everything he can to find her.
Natalia Bryant beelined it to court Monday to get a restraining order against 32-year-old Dwayne Kemp, whom she accuses of stalking her.
In the docs, obtained by TMZ, Natalia says Kemp attempted to contact her 2 years ago -- when he was 30 and she was 17. She says he's under a delusion they have a romantic relationship.
