Detectives have released an E-FIT image of a suspect they are working to identify following a series of linked sexual assaults in the Hackney Marshes area.
In each incident the description of the suspect and his actions have been very similar.
Lone women have been out either walking or jogging when they have been approached by a male on a bicycle who has grabbed their buttocks from behind, or touched their genitals, before making inappropriate comments and riding off.
Detectives have so far received 22 reports from February to June but suspect there could be more incidents and are urging any women who may not yet have spoken to police to make contact.
The suspect is described as light skinned male, possibly mixed race, aged 16/17, who is usually wearing a grey tracksuit.
Detective Constable Hannah Rodericks, Central East Command Unit, is investigating. She said: “I understand this news may cause considerable concern among the community. We in the Central East Command Unit share that concern and are doing everything we can to identify and bring to justice the person responsible.
“It is imperative that he is identified but we need the public’s help. Anyone who has information that they think can help us is urged to make contact immediately.”
Anyone who has information that could help police should call 101 ref 4216097/22.
