Detectives will carry out an anniversary appeal in Hackney one week on from the murder of 34-year-old Daniel Frederick in Shakspeare Walk.
A murder investigation had been launched after police were called to reports of an assault there at 5.48 pm on 8th January.
Daniel lived locally and was suffering from multiple stab injuries.
He died later this night after being taken to a local east London hospital.
A post-mortem examination took place on Wednesday, 10th January and gave cause of death as a stab wound.
Next of kin have been informed.
It is the fourth murder investigation underway in London this year – three of which have been fatal stabbings.
Detective Inspector Paul Considine, who is heading up the investigation, stated:
From the information I have at this time it seems that Daniel may have been mistaken for somebody else. He appears to be a completely innocent victim who was walking through the estate when he was subject to an unprovoked attacked. I urge anyone who was in the area at the time of the incident or knows who is responsible for Daniel’s murder to contact police immediately.
Anyone with information can call the incident room on 020 8345 3734 or contact the Metpolice on twitter via @MetCC
