Police are hunting a moped delivery driver after five women and a 14-year-old girl were sexually assaulted.
The suspect has been targeting women walking alone at night for seven weeks.
He was described as riding a moped and generally wearing dark clothing.
The assaults all happened within a two-mile radius in the Haringey area of north London
Detective Inspector Pete Dyche, of the Met’s North Area Command Unit, said: “We are carrying out a number of urgent enquiries as part of our investigation and are doing our utmost to catch the perpetrators.
“In each incident, the victims, who have all been females walking alone, were approached by a man riding a moped, who has followed the victims and sexually assaulted them before fleeing.
“We are keeping an open mind as to any links amongst these crimes.
“I would advise that anyone walking alone in the evening in these areas to be mindful of their surroundings and to report any suspicious activity to police immediately.”
The assaults started on March 3 and took place between 8.45pm and 1.17am, and the latest attack happened on Thursday.
