Why investigate women’s march organisers?

I REFER to the statement issued by the Jawatankuasa Hari Wanita Sedunia 2019 on March 14.

According to the statement, the organisers of the International Women’s Day march that took place in Kuala Lumpur on March 9 are being investigated by police under Section 9(1) of the Peaceful Assembly Act (PAA 2012) and Section 4(1) of the Sedition Act.
