The officers were accused of sexual offenses, including gang-raping a drunk woman and masturbating on the sideline.

According to a report filed by a 31-year-old woman, she was sexually assaulted in a party room at Mirador Mansion in Tsim Sha Tsui on July 8.

The victim reportedly met a couple, who was a member of the CSD, in Lan Kwai Fong last year and became friends.

They were later invited to the party where they socialized with the couple and the seven correctional officers.

The couple left the party early, leaving the woman behind.

She later blacked out after consuming alcohol and woke up the next morning alone and naked inside the party room, suspecting she had been sexually assaulted.

The Yau Tsim district crime unit has taken over the investigation and is currently probing the case.
