A second man has been charged with the savage murders of two French students, Scotland Yard said.
Daniel Sonnex, 23, of Peckham Park Road, south-east London, was charged with the murders of Laurent Bonomo and Gabriel Ferez, who were found after an explosion at a rented bedsit in New Cross, south London, on June 29.
Mr Bonomo had been stabbed nearly 200 times while Mr Ferez had suffered nearly 50 knife wounds.
Sonnex will appear at Wimbledon Magistrates Court on Monday where he will also face a charge of perverting the course of justice.
Sonnex was arrested in Peckham on Thursday evening. Scotland Yard had issued an alert to find him less than an hour before.
He is the second man to be charged with the murders. Nigel Farmer, 33, of no fixed address, appeared at Greenwich Magistrates' Court on Thursday.
He was accused of both murders, arson and attempting to pervert the course of justice. He was remanded in custody until October 16 when he will appear at the Old Bailey.
A 35-year-old man and a 25-year-old woman arrested at an address in Streatham, south London, on Wednesday have now been bailed to return on dates in July and August respectively, pending further inquiries.
It is understood that the 35-year-old man is Sonnex's brother, Bernard.
Mr Bonomo and Mr Ferez, both 23, were in the second year of masters degrees at the Clermont-Ferrand Polytech in the Auvergne region of central France. Both had been selected for the Undergraduate Opportunities for Research Programme, a three-month project on DNA, in the life sciences department at Imperial College, London.
