A devout Catholic and mother is the subject of a five-month police investigation - after she was accused of calling a transgender woman a 'he' on Twitter.
Caroline Farrow, a broadcaster and writer for Roman Catholic newspapers, said she had a phone call from an officer on Monday asking her to attend an interview.
Mrs Farrow, 44, said she may have posted the suspect tweet following an appearance on Good Morning Britain last September, during which she took part in a debate on transgender children.
She said she was prepared to go to jail, adding: 'I don't know what I am suspected to have done. The only thing I can think of is that I may have referred to a 23-year-old transgender woman as someone's "son".
'I try at all times to be polite on Twitter, but it is my belief on both a religious and scientific basis that you cannot change the sex into which you were born.'
She added the officer said her tweets had 'misgendered' an individual by using the wrong pronoun, which could be an offence under the Malicious Communications Act.
