A man aged 31 has been arrested on suspicion of murder after two people were killed in a quadruple stabbing at a London business.
The Metropolitan Police announced the charges faced by a man from Hackney, east London, who had initially been detained following Monday's attacks in Southwark.
He remains in hospital with injuries not thought to be life-threatening, Scotland Yard said today.
Emergency services were called to Long Lane in Bermondsey at about 1pm on Monday following reports of multiple stabbings inside a commercial address.
A 58-year-old man was pronounced dead at the scene and a 27-year-old man later died in hospital.
