A murder investigation has officially been launched as police issue a further appeal for witnesses after a dad was stabbed in Greenwich.

Danny Pearce was walking along King William Walk on his way home from a jazz bar at around midnight on July 14 to 15 when two people on a moped approached him.

Witnesses heard a woman shout “no, no, no” as the 31-year-old Bromely dad was stabbed and gunshots were heard.

Police and the London Ambulance Service were called at 12.15am but Mr Pearce was pronounced dead at the scene.

A post-mortem examination on July 15 confirmed that he had died from stab wounds.

Police have launched a murder investigation and have said they retain an open mind as to the motive.

Detective Inspector Jo Sidaway, who is leading the investigation, said: "We continue to appeal for witnesses or anyone with information to come forward. We believe that Mr Pearce was approached on King William Walk by two suspects on a moped.

"One suspect is believed to have been in possession of what appeared to be a firearm, the other a knife.

"During an altercation Danny Pearce was stabbed and a firearm was discharged.

"The suspects fled the scene on the moped and the victim made his way to a nearby address to ask for help. He was pronounced dead there.

"I would like to hear from anyone who has information, no matter how insignificant it may seem."
