Detectives are hunting a serial sex offender targeting young women in north London.
In the first incident, a 15-year-old schoolgirl was walking on Rostrevor Avenue, Tottenham, when a man approached her and showed her pornography on his mobile phone on January 20.
A girl aged 12 was confronted by a suspect who exposed himself to her before making off along Linthorpe Road, Stamford Hill at 7pm on February 16.
Two hours later, a woman in her 20s was pushing her child in a buggy along nearby Kyverdale Road when he pushed her and then touched her bottom before fleeing.
The Met said none of the victims suffered serious physical harm but were left incredibly shaken and upset.
Due to the timings, locations and how the three were approached, police are treating the incidents as linked.

Officers have been speaking to members of the community and conducting additional patrols to provide reassurance.
Detective Constable Patrick Godin said: “We are doing everything we can to identify and apprehend the man responsible.
“I am asking local people to study the images and footage issued very carefully and contact us immediately if they have information that could help. Please work with us to help keep your communities safe.”
