A 26-year-old man has been arrested on suspicion of murder of a woman in the Ifield murder inquiry.
The man from London was detained on Tuesday (17 March). He is now in custody awaiting questioning.
Around 2.30pm on Friday (13 March), a Volkswagen Jetta car parked near Ifield Golf Club, Horsham, West Sussex, was reported to be on fire.
