Police stress they are not suspects but may hold vital information

Detectives investigating the murder of a man with learning difficulties in Greenford have released CCTV still images of three men with whom they wish to speak.

Dean Mayley, 24 from Northolt was attacked in Ruislip Road, Greenford at approximately 1720hrs on Friday, 7 February after getting off an E9 bus around 50 minutes earlier in The Broadway.

Officers and London Ambulance Service attended and Dean was taken to St Mary's Hospital where he died later that evening.

A post-mortem examination took place on 10 February and gave cause of death as a single stab wound to the chest.

Police are keen to stress that the three men in the images issued are not suspects, but they may hold vital information. Detectives are urging them to come forward; information that they provide will be treated in the strictest confidence.

The first two images are of two individuals who were present at the KFC in Greenford Broadway prior to the stabbing.

The third image is of a white male who walked pass Dean seconds before the murder.

Dean suffered from microcephaly which led to him having learning difficulties and a mental age of approximately nine years old. As a result, his family state that he was very vulnerable and easily led.

Detective Chief Inspector Matt Bonner, of the Homicide and Major Crime Command, is leading the investigation.

He said: "I am urging those in the images we have issued to please come forward and help us with our enquiries. Likewise there may be people who recognise these three men; don't remain silent please come forward and help us.

"I must stress that we are not treating these men as suspects and strongly believe that any information they hold can assist us with our ongoing enquires into Dean's murder."
