A man who was killed following an altercation in a North Wembley pub has been named as Graham Howe from Kenton.
Emergency services were called to a pub in Preston Road at the junction with Uxendon Crescent at 11.05pm on May 30.
Paramedics tried to save the 53-year-old but he was pronounced dead at the scene.
A post-mortem examination on June 2 at Northwick Park mortuary gave a provisional cause of death as a head injury, said Scotland Yard.
Further tests will now be carried out.
A 32-year-old man was arrested at the pub on suspicion of murder and taken to a north-west London police station.
He has since been bailed to return on a date in late June.
Enquiries into the circumstances surrounding Mr Howe's death continue.
Anyone with information is asked to contact police on 101, quoting CAD8939/30May
