Chiziem Omisa, aged 25, of Potters Bar, Hertfordshire, has been sentenced to four years and four months’ imprisonment at St Albans Crown Court after admitting sexual assault by penetration, stalking, and perverting the course of justice.
The court heard that the primary offence occurred in May 2019 inside student accommodation in Nottingham. Omisa located the female victim’s profile on Instagram, initiated contact, and arranged to meet her. During the meeting, Omisa subjected the woman to a sexual assault by penetration, ignoring her continuous requests for him to stop. In the aftermath of the attack, Omisa attempted to intimidate the victim into silence by claiming she would face expulsion from her university course if she contacted law enforcement.
The victim was subsequently identified when Nottinghamshire Police officers seized and analysed Omisa’s mobile phone. When initially questioned under caution, Omisa denied the allegations and claimed he had committed no offences. However, digital forensic analysis uncovered WhatsApp messages sent by Omisa to a friend on the day of the assault in which he boasted in detail about what he had done.
Investigators also established that while released on police bail for the Nottingham assault, Omisa created false online profiles under assumed names to stalk and harass two other young women after they rejected his advances.
Appearing before St Albans Crown Court, Omisa pleaded guilty to:
- One count of sexual assault by penetration
- Two counts of stalking
- One count of perverting the course of justice
On Thursday, 27 June 2024, the presiding judge sentenced Omisa to a total custodial sentence of four years and four months. In addition to the prison term, the court imposed restraining orders barring contact with his victims and granted a Sexual Harm Prevention Order (SHPO). Under the terms of the SHPO, Omisa is strictly prohibited from sending unsolicited friend requests or messages to women online, must declare all social media accounts and aliases to police, and must make all electronic devices available for routine inspection by law enforcement officers.
