A second man was charged Saturday with the brutal murders of two French students, who were found bound, stabbed and burnt in a southeast London flat, police said.
Scotland Yard said in a statement that Daniel Sonnex, 23, from Peckham, also southeast London, was charged with the murders of Gabriel Ferez and Laurent Bonomo, whose bodies were discovered in nearby New Cross on June 29, the AFP reported.
He was also charged with attempting to pervert the course of justice and will appear in court on Monday morning, the force added.
Nigel Farmer, 33 has appeared in court Thursday charged with the murders as well as arson and attempting to pervert the course of justice. He was remanded in custody until a further hearing on October 16.
Earlier Saturday, police released on bail a 35-year-old man and a 25-year-old woman until unspecified dates in July and August pending further enquiries.
Ferez and Bonomo, both 23 and biochemists, were on an exchange programme from their university in Clermont-Ferrand, central France, with London's prestigious Imperial College.
They had been due to return home at the end of this month.
On the evening of June 29, the emergency services were called out to a fire and reports of an explosion at a ground-floor studio flat rented by one of the students.
After they put out the fire, they found the bodies of the two men. They had been bound, repeatedly stabbed in the head, neck, torso and back then set alight.
Their deaths shocked hardened detectives and coincided with growing concerns about knife crime and violent gang culture in the British capital, particularly among young people.
Bonomo was stabbed nearly 200 times -- up to 80 of the wounds after he was dead -- while Ferez suffered nearly 50 knife wounds.
Six days before they were found, Bonomo disturbed an intruder stealing a laptop computer from the flat, which is still being searched by forensic investigators.
Experts found no evidence of forced entry after the killings. Two handheld games consoles were also taken and credit cards are missing..
