The parents of suspected so-called "honour killing" victim Shafilea Ahmed have been arrested on suspicion of her murder, police sources have said.
Shafilea went missing from her home in Warrington in September 2003, aged 17. Her decomposed body was found in the River Kent in Cumbria in January 2004.
A coroner ruled in 2008 she had been unlawfully killed. No-one has ever been charged with her murder.
Iftikhar, 50, and Faranza Ahmed, 47, were arrested in Warrington earlier.
