In 2020, the Offender Database recorded that 21-year-old Gemma Watts was sentenced for a sophisticated and wide-ranging grooming campaign in which she posed as a teenage boy. Following a joint investigation by the Metropolitan Police and Hampshire Police, the defendant—of Enfield, North London—pleaded guilty to seven counts of sexual assault and grooming. It was reported that Watts adopted the persona of a 16-year-old boy named “Jake Waton,” using Snapchat, Instagram, and WhatsApp to target up to 50 girls as young as 14 across the United Kingdom.
The investigation established that Watts used her own photographs while disguised with a baseball cap and baggy clothing to maintain the “Jake” identity. The Metropolitan Police reported that she travelled the country by train to meet victims in Hampshire, Surrey, Plymouth, and the West Midlands. The prosecution reported that Watts was so convincing in her male persona that she spent time with some of the victims’ parents, who remained entirely unaware that she was an adult woman.
Judicial Findings and Investigative Detail
The court reported that Watts showed no remorse for the “life-changing” impact her deception had on her young, innocent victims. Winchester Crown Court heard that for many of these girls, this was their first relationship, and the discovery of the truth was deeply traumatic. The investigation established that Watts continued to offend even after police became involved, breaching a Sexual Risk Order just two weeks after it was issued in November 2018.
Detective Constable Phillipa Kenwright stated that Watts was finally caught after a victim was reported missing in the West Midlands; British Transport Police (BTP) officers initially believed Watts was the 16-year-old “Jake” and were in the process of taking her home before the link was made. For her actions across the country, including assault by penetration and grooming, Watts was facing an immediate custodial sentence. The judge noted that the case highlights the extreme dangers of social media and the ease with which perpetrators can “mask” their true identity to groom children.

Monitoring and Public Protection
Watts is managed as a high-risk Category 1 dangerous predator within the North London area. Due to the nature of her conduct, which involved a high level of premeditation and the use of physical disguises to facilitate sexual assaults, her management is a maximum priority. Authorities state that her ability to dupe both children and their parents indicates a manipulative personality that requires the most intensive level of supervision by the MOSOVO (Management of Sexual Offenders and Violent Offenders) unit.
As a registered sex offender for life, Watts’ details are permanently logged on the national police database. Authorities state that her SHPO includes strict conditions prohibiting the use of social media under any name other than her own and mandating the disclosure of all internet-enabled devices. Any attempt to re-create the “Jake Waton” persona, any unauthorised contact with minors, or any presence near schools in Enfield or the wider London area will result in immediate arrest to ensure the ongoing safety of the public from a confirmed serial groomer.
