A 32-year-old man has been arrested by
police in Bristol in connection with threats
made on Twitter.
He is suspected of offences against two
women, who reported the allegations on 25
and 29 July.
The BBC und
erstands the arrest is in relation
to threats made against Labour MP Stella
Creasy and feminist campaigner Caroline
Criado-Perez.
They are among a number of prominent
women recently targeted by so-called trolls.
It is the third such arrest since allegations
surfaced two weeks ago.
The man was arrested under the Protection of
Harassment Act and is due to be taken to a
Bristol police station, the Metropolitan Police
said.
Extra staff
There have been calls for Twitter to do more
to prevent abuse after anonymous users of the
site sent messages to well-known women
threatening bomb and rape attacks.
Female journalists, columnists and the
historian Mary Beard were all singled out.
Last weekend some users boycotted the site to
raise awareness of "trolling" - the practice of
insulting or intimidating others, usually under
a pseudonym, to get a reaction.
It attracted media and police attention after
campaigner Ms Criado-Perez was targeted by
trolls when she successfully lobbied for a
woman's face to be pictured on UK bank
notes.
Twitter has drafted in extra staff to deal with
the levels of abuse and has moved to clarify its
reporting procedures.
