A homeless man has been arrested on suspicion of attacking four women in a seven-hour rampage in Sham Shui Po.
The 41-year-old suspect, surnamed Cho, was held on Thursday based on descriptions by his victims and footage from security cameras.
Police are looking into the motive for the random attacks across three housing estates last Friday, Ming Pao Daily reports.
The man has an assault record and has been previously held for impersonating a police officer.
He will be presented in a police lineup before his alleged victims.
The four women, aged 17 to 33, were attacked in Fu Cheong Estate, Wing Cheong Estate and Nam Cheong Estate.
The first one, a 17-year-old student, was hit in the head with an electrical plug as she walked home from school.
The others were also hit in the head or face, one seriously enough to require surgery.
The victims do not know each other and had no previous encounter with the suspect, investigators said.
Police have increased patrols in the area amid heightened tensions among residents over their safety.
