Bobby Brown -- Nick Gordon Can See Bobbi Kristina, BUT ONLY IF ....

9:15 AM PST -- Gordon's attorney says his client his legal team advised Nick to reject Bobby Brown's conditions in order to visit Bobbi Kristina. He says Nick has repeatedly offered to meet with Bobby in private to clear the air, rather than go through lawyers, but the singer turned Gordon down.

Bobby Brown is calling BS on Nick Gordon for suggesting the family won't let him see Bobbi Kristina ... but when you read between the lines it sounds like there's a string attached that Nick won't touch.

Brown lawyer says, "To address the continued and never ending media requests for comment about Mr. Gordon's requests to visit Bobbi Kristina, let me be very clear, Mr. Gordon was offered an opportunity to potentially visit Bobbi Kristina and he declined to meet the terms of any possible visit."

The lawyer won't say what "term" Gordon must meet, but it's pretty apparent. TMZ broke the story there's a criminal investigation because Bobbi Kristina had visible injuries when she was rushed to the hospital, and Nick is the target of the investigation. Seems obvious ... Brown wants Nick to talk to cops.

The lawyer certainly hinted he wants Nick to sit down with police, saying, "We are only concerned with individuals that can help Bobbi Kristina and bring resolution to the investigation."

As far as we know Nick has not been interviewed by police and the investigation is ongoing.

Nick made a public plea Saturday night to allow him in the hospital, claiming he's the one who can bring his girlfriend back to life, but Brown's lawyer scoffs, saying, "Obviously Mr. Gordon is not as desperate to visit Bobbi Kristina as he wants the world to believe."
