THE devastated father of Sian O'Callaghan wept yesterday as he told of her family's agony.

Speaking for the first time since his daughter was killed after leaving a nightclub, Mick O'Callaghan, 51, said they faced "dark days ahead" over their horrendous loss.

With son Liam, 24, by his side, the 51-year-old builder added: "Our pain is raw."

Mick spoke as cabbie ­Christopher Halliwell, 47, appeared in court accused of murdering Sian, of Swindon.
