Two men accused of attacking former Ming Pao chief editor Kevin Lau Chun-to were charged with wounding and theft on Wednesday.
The two Hong Kong residents, both aged 37, will appear in Eastern Court in Sai Wan Ho on Thursday.
The two suspects were arrested in Dongguan, Guangdong province, after Hong Kong police sought help from mainland authorities about two weeks ago. Hong Kong police were informed about the arrests on March 9.
The pair were transferred to the city on Monday.
On Tuesday suspects were escorted under the watchful eyes of more than 100 police officers to seven locations across the city to help reconstruct the attack.
Hong Kong police have arrested nine other people in various parts of the city during the course of the investigation. The eight men and one woman, aged from 30 to 57, who are all Hong Kong residents, were later released on bail and are required to report back to police in mid-April.
Lau, 49, was attacked as he got out of his car in Tai Hong Street, Sai Wan Ho, on February 26.
The attack left his internal organs exposed and damaged nerves in his legs. He is still recovering from his injuries in Pamela Youde Nethersole Eastern Hospital in Chai Wan.
The attack followed Lau’s controversial removal as Ming Pao chief editor, which sparked a march in support of press freedom that saw thousands take to the streets.
