The office of pro-Beijing lawmaker Junius Ho was ransacked in Hong Kong on Monday after he was pointed to as the possible mastermind behind Sunday’s attack on metro commuters by a group of armed thugs.

At around 10:30 pm on Sunday night, dozens of men, dressed in white and wearing masks, ran into the Yuen Long MTR station and began savagely attacking people with wooden poles and metal rods.

They are believed to have targeted protesters who were returning home from a large anti-extradition rally. Police did not arrive in force at the scene for more than 30 minutes. By that time, the thugs were all gone.

Video has circulated online showing Ho, who lives in Yuen Long, shaking hands with some of the men dressed in white, giving them a thumbs up, and thanking them for their “hard work.”

It’s unclear exactly what Ho was thanking the men for but the clip has made some wonder if he was the one who orchestrated the attack.

At a press conference at noon on Monday, Ho insisted that he had nothing to do with the attack, declaring that it was perfectly normal for him to shake hands with his constituents.

However, he didn’t distance himself too far from the attack, saying that it was only natural that the residents of Yuen Long would try to “safeguard their own community,” calling the anti-extradition protesters, “rioters.”

Within hours of the presser, a group of those protesters had broken through the glass walls of Ho’s office at the Tsuen Fung Centre Shopping Arcade in Tsuen Wan and totally trashed the place.

Ho is no stranger to controversy. Back in 2017, he got into some trouble for saying that activists who called for Hong Kong to break away from China should be “killed mercilessly.”
