Five young men arrested in connection with the death of 18-year-old knife victim Isschan Nicholls have been released without charge.

Police issued a further appeal last Thursday, including a �20,000 reward for anyone with information leading to a prosecution, as they continue to investigate the death of Mr Nicholls.

He was stabbed after being attacked by up to 15 youths in Parnell Road, Bow, on January 13 last year and died two days later from his injuries in the Royal London Hospital, Whitechapel.

A 19-year-old man was initially arrested with nine other men and two women.

All were released with no further action but the 19-year-old was subsequently re-arrested on September 8 and four new arrests were made of two 18-year-olds and two 17-year-olds.

All were released with no further action after returning to an east London police station on Saturday.

Isschan’s mother, Jennifer Williams, made an appeal in the East London Advertiser last Thursday for anyone with knowledge about Isschan’s attack to come forward.

She said: ““It has been a year since Isschan was tragically taken from us and this alone has had a major affect on our lives. Coupled together with the fact that no one has yet been charged it makes the whole incident even more unbearable.

“Someone knows who did this. Please come forward.”

Anyone with information can call the incident room on 020 8721 4054 or contact Crimestoppers anonymously on 0800 555 111.
