Detectives investigating a series of sexual assaults that they believe to be linked have released new CCTV footage of a man they would like to speak to.
Officers are investigating up to 25 sexual assaults committed in south London, mainly in Lewisham and Greenwich boroughs but also including Southwark, Bromley and Bexley.
The assaults all took place in the past year, typically during the rush hour periods - between 07:00 and 09:00hrs and 16:00 and 18:00hrs roughly - with young women and girls the victims.
The first incident is believed to have taken place on 16 October 2016 - a 13-year-old girl was sexually assaulted in Foxfield Road, Orpington BR6 at around 09:15hrs.
Since then, police have received reports about similar offences that may have been committed by the same suspect.
The last reported assault was committed on Wednesday, 22 November. A 15-year-old girl reported being sexually assaulted in Sandbourne Road, Brockley just after 0830hrs. From this incident, officers were able to recover CCTV footage showing a male that they would like to trace as part of their investigation.
He is described as a middle-aged white man aged in his 40s, with blue eyes.
Police have increased patrols in the areas where offences have been reported, and are working with local schools to reassure pupils and parents.
Detective Chief Inspector Andrew Furphy of Lewisham police, leading the investigation, said: "These offences have been traumatic for the victims, all of whom have been young females going about their daily lives.
"There is a strong possibility that these incidents are part of a linked series of attacks as a number of victims have provided very similar descriptions of the attacker - a white man aged between 40 and 50.
"It is also notable that none of these offences have taken place over a weekend and many of them have been committed during the morning and evening rush hours
"Our officers have been working tirelessly to apprehend the suspect, but we need the public's help. CCTV shows footage of a male that we would like to speak to who we believe may be able to assist our investigation. If this is you or if you know who this person is, please contact us.
"We are also aware that there might be further victims who have not yet spoken to police; if you are a victim, or know someone who has been a victim of a sexual assault, I can assure you your information will be treated with the strict confidence and sensitivity. We also have access to specialist support."
