Chris Brown is being investigated by child protective services

And though he hasn't yet been charged over the incident, officials from Los Angeles' Department of Children and Family Services (DCFS) went to speak to the 27-year-old singer on Thursday (22.09.16) afternoon.

Sources told TMZ Chris believed Nia had filed a complaint against him following Baylee's accusations, which he has repeatedly insisted are not true.

The DCFS representatives were accompanied by police officers on their visit to the 'Beautiful People' hitmaker's house, but the singer reportedly refused to speak with the investigators or even let them enter his security gate.

The visit comes shortly after it emerged the singer has had to postpone tour dates in Tokyo because he has been refused a visa to enter Japan because of the ongoing legal investigation.

The 'Yeah 3x' star has previously maintained "the truth" about Baylee's allegations against him will come out eventually.

He said recently: "I cannot wait till the truth comes to light about this incident and this situation. You know, because my character's been defaced and who I am as a person and [my] integrity.

"I'm glad all my real supporters know me, and know the truth and see the truth."

It was previously claimed his accuser had texted a friend and vowed to set the singer up after he told her to leave his house, and Chris and his legal team have made the messages public.

One allegedly read: "This freak Chris Brown is kicking me out of his house because I called his friends jewelry fake. I'm going to set him up and call the cops and say that he tried to shoot me and that will teach him a lesson I'm going to set his ass up.(sic)"

Chris' lawyer, Mark Geragos, has insisted police haven't found a gun or jewellery matching the description given by Baylee when they searched the house.

He said: "There was a search that was done. They went in, and said they had a description of the piece of jewellery. Not found in the house. They went in, a gun, not found in the house."

And surveillance cameras on the 'Beautiful People' singer's property are also being investigated, and Mark insists they will further prove his client is telling the truth.

He said of the footage: "There's no Chris Brown waving a gun. No Baylee looking at a box of jewellery."
