POLICE have launched a fresh appeal for information a year after have-a-go hero Sukhwinder Singh was stabbed to death chasing bag thieves.

The popular father-of-one was knifed through the heart as he tried to tackle two black men wearing hoodies in Uphall Road, Barking. He was 31.

Police arrested five men in the wake of the murder but all were released without charge. A �20,000 reward put up in May has not led to further arrests.

A 28-year-old woman was walking home from Barking Station when two black men wearing hoodies stole her brown handbag containing her silver Samsung mobile.

Sukhwinder, a builder from Harts Lane, Barking, gave chase at 6.40pm on January 8, 2010, but was knifed and later pronounced dead at Royal London Hospital.

The bag and the phone were thought to have been temporarily dumped in Charlton Crescent, Barking, but have never been recovered.

* Anyone with information is urged to call 020 8345 3775 or Crimestoppers on 0800 555 111.
