A man has been stabbed by an attacker matching the description of a knifeman who injured four people in one night.

The victim, aged in his 30s, was left with life-threatening injuries when he was stabbed in Fairfield Road, Enfield, north London at around 5am on Tuesday, just yards from the scene of a previous attack at the weekend.

Police have said the latest incident has "not yet been formally linked" to a series of knife attacks in the area, but the culprit in all five is a tall, skinny black man wearing a hooded top.

Two men who were arrested on suspicion of causing grievous bodily harm remain in custody, and investigators have until later on Tuesday to interview them.

Detective Superintendent Luke Marks said: "I am aware that events from the weekend have caused a huge amount of worry and concern among the community, and that this incident will cause further alarm.

"While at this stage the incident has not yet been formally linked, the location and manner of this attack will be of concern to the public.

"Our advice continues that that public to remain vigilant, and to contact police regarding anyone acting suspiciously.

"You will see additional uniformed patrols in the Edmonton area; if you have any concerns, please speak with my officers immediately."

A large police cordon is in place blocking off several streets in the area, with uniformed officers standing guard. Investigators in forensic suits are taking photographs of the area and looking for clues. A black jacket, metallic blanket and medical equipment marks the scene in Aberdeen Road, where the victim was found.

Scotland Yard said the victim, in his 30s, was reported to have been walking with a companion when he was attacked in Fairfield Road. He then made his way to Aberdeen Road, where he was found by police.

Mike Kalongi, 28, who lives near the scene of the stabbing, said: "It's getting a bit close.

"It's a bit scary. I usually go to the gym at night, but over the last few days I decided not to.

"I'm going shopping. I usually have my headphones on but I want to stay aware and try not to be a victim.

"It's scary. It's really scary."

Tarek Elmadkhoun, 32, said: "It happened just outside my door. My wife heard some talking at 5am. She's a bit worried.

"I just moved here one week ago. To be honest it's a bit worrying.

"My wife doesn't speak English. She doesn't know what to do."

The Times reported that local schools had banned children from leaving the grounds during their break time as a safety measure.

The latest stabbing follows attacks on four people in the Edmonton area of Enfield over the weekend, that left two critically hurt and one with potentially life-changing injuries.

Police believe that a single male suspect who may have mental health issues was acting alone in the attacks, and there is nothing to suggest they are terror-related.

The suspect is described as a skinny black man who is approximately 6ft 3ins tall and wearing dark clothes.

At the weekend a 45-year-old woman was the first victim when she was stabbed once in her back at about 7pm on Saturday in Aberdeen Road, and left in a critical condition.

The final attack occurred at about 9.40am on Sunday in Brettenham Road where officers found a 29-year-old man with a stab injury to the back.

His injuries are life-threatening.

Update: A man in his 30s has been arrested in connection to the incident.
