The head of Hong Kong’s leading journalists group was sentenced on Monday to five days in jail for obstructing police officers in September last year after a case seen by some critics as a further blow to media freedoms in the financial hub.

Ronson Chan, chairperson of the Hong Kong Journalists Association, was detained and handcuffed by two plainclothes officers while covering a story after he failed to hand over his personal identity card.

Chan, who pleaded not guilty, earlier told the court that he had asked the police to show them their warrant cards before handing over his document, which all Hong Kong residents must carry.

Magistrate Leung Ka-kie found Chan guilty, saying that a fine instead of jail would not reflect the gravity of the offence. Leung also refused to consider community service instead as she said Chan showed no remorse.

Leung did grant Chan HK$30,000 ($3,838.48) bail after his lawyers said he would appeal. The journalist cannot leave Hong Kong and had to surrender his travel documents.

Speaking after the hearing, Chan said he was not surprised by the custodial sentence.
