The body of a man was found at a canal in Park Royal while an outdoor function was being held at a pub nearby.
Emergency services, including several fire engines, police cars and an incident response unit, were seen near the Grand Junction Arms pub in Acton Lane on Saturday afternoon (March 24).

The member of staff from the Grand Junction Arms, who did not wish to be named, said: "It's not the first time it's happened, it's now the fourth time I've seen it.
"We're across on the other side of the canal. We were hosting a function at the time, [they] were sitting outside eating a meal and I had to go out and warn them about what they were about to see.
"It was all over by about 3-4pm.
"I always tell my customers not to walk [along the canal] at night as people have fallen in before."
London Ambulance Service said it was called at 1.48pm to reports of "an incident" in Acton Lane.
Their spokesman said: "We sent two single responders in cars and an ambulance crew.
"Sadly, a person was dead at the scene."
