Getting close --- following is someone's post on FB:
Jagwinder Singh: I know who he is( but not his name nor whereabouts)He hangs out regularly at one of the provision shops after work. But he's not been there again since the incident. He's a very humble and friendly guy. Even when drunk he's a "happy drunk" and has helped to break up many fights between migrant workers on Sunday nights. And he's not Bangladeshi, he's Indian.
Still no one has identified the man.
He could be a police detective?
Certainly, he is a 'leader' of sorts, someone who has some experience in organising/leading some group of people.
