Two women and seven children have been attacked in spate of sexual assaults in south London.
Police say each of the victims was attacked in the last three months in the Greenwich and Lewisham areas of London.
Each assault took place in the middle of the day between June 30 and October 16 with three taking place within half an hour on October 5.
Police are considering the possibility that all the attacks are linked and have released CCTV of the latest incident - in Honor Oak Road on Monday at 4pm - in a bid to help identify a man.
Scotland Yard said patrols in the areas have increased and officers are speaking to local schools to reassure pupils and parents.
Anyone with information is asked to call police on 101 or Crimestoppers anonymously on 0800 555111.
