Caroline Criado-Perez (right) says the abuse started after her successful bank note campaign
A man has been arrested after a feminist campaigner was deluged on Twitter with abuse and threats of rape, Scotland Yard has confirmed.
The 21-year-old was detained earlier in the Manchester area on suspicion of harassment offences.
Caroline Criado-Perez faced abuse after successfully campaigning for a woman’s face to appear on UK banknotes.
Labour has complained to Twitter about what it says was an “inadequate response” to the abuse.
Ms Criado-Perez, who had appeared in the media to campaign for women to feature on banknotes, said the abusive tweets began the day it was announced that author Jane Austen would appear on the newly designed £10 note.
She reported them to the police after receiving “about 50 abusive tweets an hour for about 12 hours” and said she had “stumbled into a nest of men who co-ordinate attacks on women”.
Via her Twitter page on Sunday evening she said she was at a police station making a statement and that there were “many more threats to report”.
The Metropolitan Police said an allegation of “malicious communications” had been made to officers in Camden on Thursday.
An online petition set-up in response to the abuse called on Twitter to introduce a “report abuse” button and received thousands of signatures.
Labour said on Sunday that it had written to Twitter complaining that it had been “weak” to tell Ms Criado-Perez to take her complaints to the police.
“Of course it is right to report such abuse to the police,” shadow home secretary Yvette Cooper wrote.
“But social media platforms also have a responsibility for the platform they give users.”
Ms Cooper said Twitter should carry out a full review of its abuse and complaints policies.
Guidelines published by the Director of Public Prosecutions, Keir Starmer, in June said there should be a “high threshold for prosecution in cases involving communications which may be considered grossly offensive, indecent, obscene or false”.
