A man who was murdered in Old Trafford was stabbed as he tried to come to the aid of a friend, police said.

The man, now named as Salah Eldin Adam, was declared dead after the emergency services were called to Kings Road at around 7.45pm on Wednesday.

In an update on Friday, police said it is thought Mr Adam was stabbed as he tried to come to the aid of a friend who was chased by two men on bicycles.

DCI Gina Brennand, of GMP’s Major Incident Team, said: "I would like to pay tribute to the victim who did his best to save a friend in danger. 

"I offer our sincerest condolences to his family who've experienced such devastating trauma on Wednesday. On behalf of GMP, our thoughts continue to remain with them at this time.

"We appreciate there are limited details at this stage, but we are working with the theory Salah was assaulted with knives at an address on Kings Road, Old Trafford, as he tried to assist a friend who was being attacked in a rear garden by two young men who had approached them on bikes – one being a black mountain bike and another being a yellow [Bee Bike].

"Through enquiries so far, we believe there were approximately five people in the area at the time, who officers believe were wearing dark clothing. They are known to use bicycles and we are keen to speak to them as they may be able to help with our enquiries."

"We owe it to the victim and his loved ones to try to find answers in the timeline leading up to his death, even the smallest piece of information in cases like this can make a big difference."
