A man who allegedly threatened Gina Miller, the architect of the Brexit legal case, has been arrested.
The 50-year-old has been detained in west London today on suspicion of racially-aggravated malicious communications and remains in custody, the BBC reported.
A complaint was made about the abuse in November.
After Miller won the Supreme Court case yesterday, she spoke about the abuse she had received, saying she had "been shocked by the levels of personal abuse that I have received from many quarters over the last seven months for simply bringing and asking a legitimate question.
"I sincerely hope that going forward that people who stand in positions of power and profile are much quicker in condemning those who cross the lines of common decency and mutual respect."
This is the second arrest police have made in relation to threats made towards Miller, Sky News said, after a 55-year-old man was arrested in December.
The Metropolitan police have also sent "cease and desist" notices to other individuals in the UK.
These notices advise their recipients not to continue with their behaviour, or else they will face police action.
