In an interview with CGTN a few days ago, Ho shared his views on possible attacks people will face.
"You never know when the black-clad will come, if they want to mobilize the villains to launch an attack against you. They could easily do it. So the black-clad or the rioters, the villains may come out from nowhere, and without giving you any prime warning."
The attack on Ho, who is running in Hong Kong's upcoming District Council election, came amid more than five months of sometimes violent political unrest in the Asian financial hub.
Lo Chun-yu and Chiang Ching-man are also contesting for the seat, ahead of an election to be held on November 24.
