Sri Lankan human rights advocate Father Reed Shelton Fernando has witnessed arrests before, but none quite like the one in front of his eyes in Mongkok on Monday.
Joining curious onlookers, he peered down from the walkway between the KCR and MTR stations and saw two policemen struggling with a young man on the pavement.
The Catholic priest leaned on the railing and stared: five years of campaigning against police torture of prisoners in his country had him intrigued as to how law enforcement was carried out elsewhere. He was unprepared for what happened next.
Quickly, the man was overpowered and his hands cuffed behind his back; then he was lying on the ground on his front, one of the policemen kneeling beside him and calming him with pats on the back and softly spoken words.
It was a revelation for Father Fernando.
'If this had happened in Sri Lanka, it would have been a very violent incident,' he observed. 'The police would have fired shots from their guns here and there and if the man had resisted arrest, blows would have rained down on him - he would have been attacked.
