A woman found dead outside Rockingham Police Station on Thursday morning had been released from police custody about six hours prior to being found dead in a garden bed outside the station. Police have described the woman’s death as tragic and non-suspicious as internal investigators now probe the lead-up to the tragedy. The circumstances surrounding the woman’s death are still being investigated and a cause of death has not yet been released. But at a press conference on Thursday Assistant Commissioner Allan Adams said the woman had been “dealt with” by police earlier in the evening for a drink driving matter. He could not say where, how or when the woman was initially arrested. He said the woman was released by police from the station about 12.30am before being found dead outside the station in a garden bed about 6am. “Early investigations have found police dealt with this individual during the late night of yesterday and early this morning for a reasonably routine traffic matter, drink driving,” Mr Adams said. “And the woman was released from police custody at about 12.30am early this morning to be summonsed to appear in court at a later date. “At about 6am this morning police returning to the police station have found the woman deceased.” Mr Adams said there were no suspicious circumstances and no other parties involved in the woman’s death. He said after being released from police custody, police were of the understanding a family member would pick the woman up from outside the station. He said police spoke with a relative at the station around 1am who told officers he was there to collect the woman, and who was trying to contact her via telephone. “As you can appreciate this is a tragic incident for a number of people close to this woman, but also the police officers that responded,” Mr Adams said. “It has certainly impacted a number of the people that responded.” Mr Adams said internal affairs investigators were at Rockingham Police Station currently examining the woman’s interactions with police prior to her being found dead. “The nature of the incident, the fact someone was in police custody and then soon after passed away, that is automatic recognition by internal affairs to come and have a look at those circumstances to make sure there wasn’t any involvement of police or any action of police that may have contributed to that,” he said. In a brief statement issued earlier on Thursday police confirmed the woman had been found dead outside the Whitfield Street facility on Thursday morning. “Police are investigating the tragic death of a woman outside Rockingham Police station early this morning,” the statement said. “At this stage there does not appear to be any suspicious circumstances surrounding the death. “However, this matter will be overseen by internal affairs unit as a matter of policy.” A witness said they saw a body covered up under a tarp.
