Over 200 Sikhs from around the UK gathered in Edinburgh on Sunday to hold a two-hour prayer vigil.
The arranged vigil called for religious tolerance
It took place in an area of Pilrig Park where a young Sikh boy was attacked last week.
A gang cut off the 15-year-old's hair - an act considered deeply offensive to the Sikh religion.
The racial attack by four white youths on Tuesday evening has been described by police as a "sustained and unprovoked assault".
The youngster had been subjected to racial abuse in the park before being kicked to the ground.
A statement from the event organisers, which includes the Sikh Human Rights Group, said: "We are praying that the intolerance we are experiencing does not become part of an unending cycle of uncontrollable hate and retribution in our society."
Later the man leading the investigation into the attack indicated he was confident that arrests could be made soon.
Ch Insp Keith Chamberlain, of Lothian and Borders Police, said officers wanted to make sure the attack was not "symptomatic of something larger than just a mindless act of assault".
He said: "I'm very, very much encouraged with the way the investigation's gone - thanks very much to the public support that we've had - and I'm very confident we'll get a positive outcome."
