A woman who was a victim of upskirting said a change in the law is needed to stop sexual harassment being treated as a "public nuisance".
The woman, in her mid-20s and from the Greater London area, became a victim when she saw two men take and then share indecent images of her on their phones.
She said she obtained evidence of the suspects' behaviour and presented it to the police, but officers were unable to take the matter further.
The victim said a change in the law would have seen her case result in a successful conviction.
Recalling her own experience, the victim said she felt totally out of control.
She said she was confident of upskirting becoming enshrined in law in its own right - in a similar way to revenge porn.
