Tony Wang, the general manager of Twitter in the UK, said the company had "engaged with the relevant parties" over complaints of online harassment against a feminist campaigner.
To protect our users' privacy, we don't talk publicly about individual cases, but we have engaged with the relevant parties.
An option to report abuse from within Twitter apps and websites would be launched soon, he suggested:
We continue to listen to feedback and are working hard to bring the report button currently in iOS and mobile web to other major platforms.
A man arrested on suspicion of Twitter harassment was bailed this afternoon, police said earlier.
