Excerpt:
A second person has been arrested as part of a nationwide police crackdown at airports launched to save girls from female genital mutilation.
The 44-year-old man was detained in Swansea on suspicion of conspiring to commit FGM on a 13-year-old girl who returned to Heathrow on a flight from Sierra Leone.
A 38-year-old woman who was travelling with the girl had already been arrested and questioned by Met detectives on the suspicion of committing the same offence.
