Police are appealing for information after a 41-year-old man was stabbed in an apparently unprovoked attack on Bankside near Southwark Bridge early on Friday morning.
The victim, a Canadian IT expert who lives in Southwark, was walking along Bankside between The Anchor Bankside pub and Southwark Bridge when he was approached and assaulted in the ten minutes after midnight on Friday 23 March.
A Metropolitan Police spokesman said that the man suffered a single stab wound to the chest and was taken to an east London hospital where he remains in a critical but stable condition.
Detectives from Southwark Police are investigating but have been unable to discover any motive for the attack. The suspect has been described as a male, approximately six feet tall, wearing a dark or grey hooded top.
The victim was carrying a skateboard at the time he was attacked.
"This was a seemingly unprovoked and callous attack, and we are obviously extremely keen to speak with anyone who might have information that could help us to identify the culprit," says Detective Sergeant Nick Blackburn of Southwark CID.
"Were you in or around that area at that time? Or did you see anyone in that area acting suspiciously? If you believe you might be able to contribute to this investigation in any way, please do give us a call."
Any witnesses or anyone with any information should call police on 101 or 020 7232 6202. To speak anonymously to Crimestoppers call 0800 555 111.
