A 25-year-old has been arrested on suspicion of harassment by officers investigating Twitter abuse aimed at Caroline Criado Perez, 29, and Walthamstow MP Stella Creasy, Scotland Yard said.
A police statement read:
"This arrest will form part of two ongoing MPS investigations relating to allegations made to police by two separate victims, who made reports of malicious communication to police on 25 and 29 July."
The arrest comes after Labour MP Stella Creasy complained to police after she was threatened with rape on Twitter.
