A third man has been arrested in connection with Twitter-based rape and bomb threats directed at various high-profile Twitter users.
The Metropolitan Police announced it had arrested a 32-year-old man on suspicion of committing an offence under the Protection from Harassment Act 1997. The arrest, made in Bristol, was conducted by officers from the Police Central e-crime Unit (PCeU) and is said to be in connection with threatening posts made on the micro-blogging service. The Met also said that two women had made allegations against the man on 25 and 29 July.
This latest arrest comes as Twitter attempts to curb further damage to its reputation following accusations of the site taking inadequate measures against abusive tweets. Feminist campaigner Caroline Criado-Perez received hundreds of threatening tweets following her successful campaign to have Jane Austen become the face of the UK's £10 note.
The abuse then spread further to other prominent female figures including the Guardian's Hadley Freeman and The Independent's Grace Dent. MPs including Labour's Barbara Keeley and Diane Abbott called for Twitter to take immediate action.
On Monday, Twitter's UK general manager Tony Wang promised to implement new features to allow users to more easily report abusive tweets, and apologised to those who were affected.
A Twitter statement said: "People deserve to feel safe on Twitter. Over the past week, we've been listening to your feedback on how we can improve our service. You told us that we need to make our rules clearer, simplify our abuse-reporting process, and promote the responsible use of Twitter."
In addition to increased availability of an in-tweet report abuse button, the firm will also be partnering with the UK Safer Internet Centre, as well as bolstering the number of staff working on responding to abusive tweets.
Twitter has often found itself unwittingly at the forefront of the negative side of the rapid rise of social media, with many cases of libel originating on Twitter, as well as supposedly comedic tweets being interpreted as terrorism threats.
