Former Guns N' Roses star Steven Adler is back in rehab following his arrest on drug possession charges on Friday.

The rocker, who also had an outstanding warrant at the time of his arrest, was detained by cops on Friday morning after emergency services were called to a house in Hollywood following a reported disturbance.

Adler was arrested and taken into custody in Los Angeles, and released after making bail.

According to reports, Adler returned to celebrity therapist Dr. Drew Pinsky's Las Encinas rehab centre in Pasadena, California, where reality TV show Celebrity Rehab is based, over the weekend.

Adler recently participated in the second season of the VH1 reality TV series.

He has also signed up to appear in follow-up series Sober Living, which is expected to track the lives of cast members after they leave rehab.

It is not known if that show will now go ahead.
