Mother, daughter rescued from gunman in Brisbane siege POLICE have rescued a mother and daughter who had been held hostage by a gunman in a north Brisbane house for more than five hours. Inspector Sean Cryer said Special Emergency Response Team officers entered the Banyo house through an upstairs bathroom window about 4.15pm (AEST) and found the pair tied up. He said the woman in her 40s and the teenage girl were emotionally distraught but did not appear to have major injuries. Police were continuing to try to negotiate with a gunman who has been keeping them at bay since before 11am. Insp Cryer said paramedics were examining the mother and daughter, who didn't appear to know the gunman. A drone and a robot have been sent to the house, but police say they haven't been able to locate the man or sight a weapon. We're attempting to make contact with him still. We have been all along and we haven't been successful in doing that," Insp Cryer said. It's the first time Queensland police have used a drone in an operation. Insp Cryer said police were investigating whether the man was known to the male homeowner, who wasn't in the house and has been talking with detectives at the scene. Officers called to a disturbance at the Earnshaw Road house just before 11am (AEST) saw a man with what they believe was a gun and heard two shots. Neighbours were evacuated and streets cordoned off as police declared an emergency situation at 11.45am (AEST)
