British police said on Sunday they had arrested a man on suspicion of the murder of a female teacher found dead in a London park last week.
Sabina Nessa, 28, left her home in south London on the evening of September 17 to make the short walk through a local park to a bar where she was due to meet a friend. She never arrived and her body was found in the park the next afternoon.
"A 38-year-old man was arrested on suspicion of murder at around 03:00hrs on Sunday, 26 September, at an address in East Sussex," the police said in a statement.
Her killing has highlighted again public anger over violence against women, coming six months after huge public outcry when a woman was abducted, raped and murdered in south London in March by a police officer.
