Georgia police have recalled a warrant issued for Bobbi Kristina Brown's arrest as she continues to fight for her life following a near-drowning incident last month (Jan15).

Whitney Houston's only child was hospitalised on 31 January (15) after she was found unresponsive and face down in a bathtub at the Roswell home she shares with her partner Nick Gordon.

She was placed in a medically-induced coma and remains in a critical condition at Emory University Hospital in Atlanta, and the situation has since prompted cops to withdraw the arrest warrant relating to a prior traffic charge.

Executive Public Information Officer George Gordon tells UsMagazine.com, "I confirm the Alpharetta Department of Public Safety had an active arrest warrant for (Ms.) Bobbi Kristina Brown. The warrant was issued because (Ms. Brown) failed to show up for a mandatory court appearance after being cited for operating a motor vehicle with expired tag registration.

"In light of recent events involving (Ms.) Brown, we are not focused on the warrant issue.

"In fact, we asked the court to dismiss the warrant and recall it - which they did. The important issue is we hope the grieving family and friends find comfort during this difficult period."

Meanwhile, Roswell police have launched an investigation into the circumstances surrounding the 21 year old's health emergency.

Roswell Police Chief Rusty Grant reveals officials are "going to follow the evidence and see where it leads us", while a source tells People.com, "Foul play is begin investigated. Including drug use and possibly cover up to remove evidence from the crime scene."

Brown is Houston's only daughter with ex-husband Bobby Brown. Her hospitalisation occurred days before the third anniversary of her mother's death.

Houston died in a bathtub at a Beverly Hills hotel on 11 February, 2012. Her death was drug-related.
