A Hong Kong court declared media tycoon and pro-democracy activist Jimmy Lai not guilty of criminal intimidation on Thursday, ending one several cases against him after his high-profile arrest last month under a new national security law.

Thursday’s verdict was for a case that dates back to 2017 and was unrelated to his arrest. Lai, who is a key critic of Beijing, had used foul language when confronting a reporter from Oriental Daily News, a major competitor to Lai’s tabloid Apple Daily.

Police, however, only charged him in February this year.

The mainland-born media magnate had pleaded not guilty.

Dressed in a light grey suit and green shirt, he smiled after the verdict was read out and shook hands with supporters who filled the courtroom.

His case comes after he was arrested for suspected collusion with foreign forces on August 10, making him the highest profile person to be arrested under the Beijing imposed law.
