The prime suspect in the brutal killing in Japan of a young teacher, from Warwickshire, has been re-arrested on suspicion of murder and rape.
Tatsuya Ichihashi, 30, was also formally charged with abandoning the corpse of 22-year-old Lindsay Hawker.
Ichihashi went on the run after Japanese police discovered the teacher's battered and bound body buried naked in a sand-filled bathtub at his flat east of Tokyo in March 2007.
He was finally arrested at a ferry terminal in the city of Osaka in western Japan last month.
Police initially held Ichihashi on suspicion of abandoning a body, but on Wednesday he was re-arrested on the fresh charges.Related content
He can be kept in custody for another 20 days before prosecutors decide whether he should also be indicted for Miss Hawker's rape and murder.
Leeds University graduate Miss Hawker, from Brandon, near Coventry, travelled to Japan in 2006 to work as an English teacher. She was last seen alive after giving Ichihashi an English lesson in a coffee shop on March 25 2007.
The suspect was caught after it was revealed that he underwent cosmetic surgery to change his appearance at a clinic in Osaka.
After Ichihashi's arrest on November 10, Miss Hawker's father Bill called for him to be jailed for the rest of his life.
"We have gone this far and we want to see it completely through. We want to see Ichihashi locked away forever," he said.
Ichihashi went on hunger strike for a fortnight after his arrest and has refused to answer questions about Miss Hawker's death.
