A man who squirted women with fake and real semen he hid in mayonnaise bottles has been jailed for four-and-a-half years. Willbert Mukori committed 16 offences of sexual assault against 12 women, often travelling hundreds of miles to prey on his victims while on bail for earlier offences.
The 26-year-old "got a thrill" from throwing semen-like substances onto the backsides of his victims, who were mostly students wearing "figure-hugging" gym gear, a court heard. He attacked 12 victims over a seven-year period, but police believe he may have targeted many more.
He struck first in 2016 and committed 15 more offences in Birmingham between August 2021 and last September. CCTV showed Mukori attacking a young woman on the street.
Police bodycam footage also showed officers searching his car and finding a squeezy mayonnaise bottle hidden inside a shoe box which contained a substance that "had the appearance of semen". Mukori, of Kingstanding, was jailed for four-and-a-half-years with a four-year extension to his licence period.
Sentencing him at Birmingham Crown Court on Tuesday, Judge Paul Farrer KC said: "Through watching pornography you realised that you experienced a sexual thrill from watching semen or pseudo semen being deposited on women without their consent. You decided you wanted to experience this for yourself as a means of gaining sexual gratification.
"It is against that background that you carried out a campaign of sexual assaults committed against lone women. On each occasion you travelled some miles from your home.
"You remained in the area for many hours looking for potential victims. Your attacks were carried out by coming up close behind your victim and then squirting Arabic gum on to their bottoms.
“Some victims did not realise they had been attacked until they discovered the liquid on their clothes. Others noticed you following them and became anxious and sometimes scared.
“Victims believed it to be semen and felt violated as a result. Your offending was brazen. You are a predatory sex offender who targeted lone women as a means of compensating for your frustration and feelings of sexual inadequacy."
The court heard Mukori first struck in Chesterfield, Derbyshire, in 2016 when he used his own semen in the attack.
Andrew Wallace, prosecuting, said: "This defendant has a very disturbing sexual perversion, the sight or thought of expressing his semen or pseudo semen on to the bottoms of young females without their knowledge or consent. There are 16 counts straddling six years and 12 separate victims.
"Two young women were attacked twice, one three times. The first matter occurred in 2016 in Chesterfield in which the defendant used his own semen.
"She immediately thought it was semen because of the smell and thought he must have masturbated on her backside. The other matters involved a prepared substance he squirted from a bottle, made to look like semen.”
Mr Wallace said those targeted were almost all students that Mukori targeted while they walked to their halls of residence in Birmingham.
He said: "These are very much similar fact offences. Lone females, the same MO, squirting a liquid on to the bottoms of young females who are totally unaware of what is being done to them and discovering the liquid afterwards."
Mr Wallace said there was then a lengthy gap before Mukori struck again on August 1, 2021, in Selly Oak. The court heard that Mukori would sometimes kneel down and pretend to be fiddling with his shoe laces. In an interview released by police, one of the women he targeted recalled being attacked on two consecutive days in February 2022.
She said: "The second time it happened to me I was on my way back from the gym and I hadn't noticed anything being thrown at me, but when I walked past Tesco I noticed in the reflection of the window something had been thrown at my backside. I felt scared because I felt like someone must be following me, so that's when I called the police. If it hadn't happened that second time I think I would have just brushed it off and acted like it was nothing."
Another women thought she might have been the victim of a social media prank. Mukori attacked his last victim, a 39-year-old woman, on September 5 last year in Lancaster Circus. She was alerted when two men jogged past her laughing. West Midlands Police said they believed Mukori may have attacked other women and appealed for witnesses to come forward.
Detective Constable Suzanna Doidge said: “These sexual offences targeted young women who were selected by Mukori based on their appearance and attire, some who were repeatedly targeted. He was careful, methodical and planned.
"His offending spans over seven years and although there appears to be a gap in his offending I believe that there may be other victims out there who haven’t come forward. This is such an unusual case.
"The collective harassment of these female students along with repeat victimisation is concerning. We have a perpetrator who has repeatedly executed an unconsented pattern of behaviour over the course of seven years, who, whilst on police bail was re-arrested and found in possession of equipment to assist him in continuing to offend."
