"It is our understanding that Mr. Lomas has cooperated with the authorities investigating what happened involving his dear friend," Lomas' lawyer said in a statement to ABC News. "Mr. Lomas is deeply concerned for Ms. Brown and remains hopeful for her full, complete and swift recovery."
The statement continued, "Mr. Lomas' widely reported recent arrest is completely unrelated to the incident that occurred at Ms. Brown's residence and there is absolutely no relationship between the two events. He has pleaded not guilty to those charges."
After being found over the weekend, Brown was rushed to North Fulton Hospital in Roswell, where she had been treated, but sources have told ABC News that she has since been moved to the Neurology Intensive Care Unit of Emory University Hospital.
"Mr. Lomas has not been accused of anything in connection with Bobbi Kristina Brown's injuries and is a witness in this investigation," his lawyer added. "Mr. Lomas' main focus is on Ms. Brown's full recovery and he continues to pray for her and her entire family throughout this tragedy."
A couple of days after the incident, the Houston family released a statement about Brown's condition that seconded sentiments shared previously by her father Bobby Brown.
“Bobbi Kristina is fighting for her life and is surrounded by immediate family," the Houston family said in a statement. "As her father already stated, we are asking you to honor our request for privacy during this difficult time. Thank you for your prayers, well wishes, and we greatly appreciate your continued support."
Also, despite public claims from Bobbi Kristina Brown, including a 2014 social media posting that she had married Nick Gordon, her father’s lawyer said earlier this week that the two have never married.
"We are currently investigating the events that led to the hospitalization of Bobbi Kristina," Christopher Brown of Brown & Rosen LLC, legal counsel for her father, Bobby Brown, told ABC News. "To correct earlier reports, Bobbi Kristina is not and has never been married to Nick Gordon.”
