CCTV images of possible witnesses sighted near to the site of a fatal stabbing in Colchester have been released by detectives investigating the murder of a vulnerable adult.

James Attfield was found with 102 stab wounds in Castle Park at 5.45am on Saturday, March 29, and died while paramedics were fighting to save his life.

Essex Police have released a number of CCTV images of people entering the park in the hours before James Attfield was discovered.

Senior investigating officer, DCI Simon Werrett, said: “The images from this camera at the entrance of the park at Middle Mill capture a number of people possibly walking into the park.

“I would ask anyone who may have walked in this area on Friday night or Saturday morning to take a look at the pictures and see if they recognise themselves.

“Even if they are not pictured I would ask that they still contact my team to see if they might have any information which will help our inquiry. “These CCTV images clearly demonstrate that the pathways through Castle Park are used regularly at night and as such there must be someone out there who holds vital information which could help us find the person or people who attacked James so brutally and left him alone to die.”

The images show people walking in the area between 11.45pm on Friday, March 28, and 4.23am on Saturday, March 29.
