Emergency services are on scene in Plumstead helping the victim of a serious attack on Lakedale Road near the High Street. Fire fighters from the nearby station rushed to aid the man.
Witnesses report weapons being thrown after the incident as two suspects ran away, with one at least heading to the High Street.
One suspect has been arrested.
Much like this morning in Woolwich, people were taking close-up photos of the victim and emergency services working alongside. At least one photo was on Facebook in the past 15 minutes.
Not only can this impede the work of emergency services it is extremely insensitive to take pictures close-up.
It was busy on the street at the time being rush hour. If you saw anything contact police on 101.
