Ip said on social media that she got the second suspected threat letter on Friday evening as she went home after campaigning on the streets. The second letter, like the first one which contained rotten meat, was a yellowish envelope.

The return address on the back was also the same as the first one, Ip continued. According to Ip's photo, the stamp indicated that the letter was mailed from Taiwan.

"Although I have become a target for intimidation, my determination to continue the election campaign will not yield," the chairperson said.

She added she has reported the case to the police as well.

Not only Ip, but other lawmakers from the pro-establishment camp, and judges who handled social unrest cases, have recently received similar threat letters as well.

Police said such cases are altogether handled by the Organized Crime and Triad Bureau.

Ip in the coming Legislative Council election will run in the Hong Kong Island West geographical constituency. Also running in this sector, pro-democracy district councilors Fong Lung-fei and Chan Hok-fung from the Democratic Alliance for the Betterment and Progress of Hong Kong.
