A man has been arrested after death threats were allegedly made on Facebook following a TV appearance by a former Birmingham City Councillor.
Salma Yaqoob, a former Respect councillor, shared the threats with her Twitter followers after she appeared on the BBC's Question Time on Thursday.
West Midlands Police said a 37-year-old man from Corby has been arrested on suspicion of malicious communications.
He is being held by Northamptonshire police, a spokesperson said.
Ms Yaqoob stood down as a city councillor in July 2011 for health reasons.
She has often spoken out against the wars in Afghanistan and Iraq.
