Veteran social activist Koo Sze-yiu was sentenced to a six-week prison term on Tuesday for burning a flag of the Hong Kong Special Administrative Region.
He was charged with one count of desecrating the regional flag after burning it near the Convention Centre in Wan Chai on July 1 last year.
The offence took place just before a flag raising ceremony was to be held at the Golden Bauhinia Square nearby to mark the handover anniversary.
In sentencing, Eastern Magistrate Lee Siu-ho noted that Koo wanted to express his strong opinions but he said everyone should abide by the law while enjoying their right of expression. He also pointed out that he had committed the same offence before.
In mitigation, Koo said he is happy to be punished as being jailed is part of the life of an activist, and he would continue to protest against the Beijing and Hong Kong governments and fight for democracy.
Before the conviction, Koo had argued that the prosecution's video footage did not show that he was burning the flag. The magistrate agreed with him on this point, but said witness accounts from police officers and photographs were enough to proof that Koo committed the offence beyond reasonable doubt.
Koo has repeated been convicted of the same offence since the handover. He was sentenced to a nine-month prison term in 2013.
