Randy Jackson is afraid for his niece Paris Jackson's safety.

The former Jackson 5 singer is furious the 15-year-old daughter of the late Michael Jackson is reportedly still living in a psychiatric unit following her alleged suicide attempt in June and worries she is being deliberately kept away from her family.

He ranted on Twitter on Monday night (19.08.13): ''I dont like it I dont like it I dont lime it / I dont like that Paris is still in this facility. It's not right / She's been there much too long

''She is not psychotic. There is no reason for her to be in a psychiatric hospital this long away from her family / I just hate the fact that you will probably still be there on my brother's birthday. This is not good (sic)''

The 51-year-old star has vowed to investigate the suspicious goings-on and promised to keep his followers updated once he's uncovered the truth.

Randy added: ''There's something more to this there's something going on I don't like it I'm afraid for her.

''Psychiatric hospitals often make you feel as though you're psychotic when you're not. Sometimes they make matters worse / I'm going to look into this . Stay tuned (sic)''.

TMZ are now reporting that Paris' birth mother, Debbie Rowe, thinks Randy - who is the youngest of the five brothers - is delusional since the teen is not in a psychiatric hospital.

A source said: ''As usual, he's grossly misinformed. He doesn't know what he's talking about. He has no idea where she is. She's not in a psychiatric hospital.''

Earlier this month, Randy expressed his fury on the social networking site at not being asked to testify in the Jackson family's wrongful death lawsuit against concert promoter AEG Live.
