Gemma Watts: Woman posed as teenage boy to sexually assault up to 50 girls, police reveal

A woman posed as a teenage boy to sexually assault up to 50 girls, police have revealed.

Gemma Watts, 21, travelled the country by train to meet the youngsters, who believed they were in a relationship with a boy close to their own age.

Watts tied her long hair into a bun and wore a baseball cap, baggy jogging bottoms and a hoodie to convince them she was a 16-year-old boy named “Jake Waton”.

She used Snapchat and Instagram to target girls aged between 14 and 16 by liking their profiles.

Watts would share skateboarding videos, use teenage slang and flatter the girls with complimentary messages, calling them “babe” or other pet names before swapping messages and intimate photographs, eventually meeting them in person.

All of Watts’ victims believed they were in a relationship with a teenage boy until police revealed she was an adult woman.

Her act was so convincing she even spent time as “Jake” with some of the girls’ parents.

Watts, who lives at home with her mother in Enfield, north London, is facing jail at Winchester Crown Court on Friday after pleading guilty to seven sexual assault and grooming charges.

The offences relate to four girls, including a 14-year-old from Hampshire and three 15-year-olds from Surrey, Plymouth and the West Midlands.

Detective Constable Phillipa Kenwright, from the Metropolitan Police, said: “It’s been life-changing for all of the victims involved. They believed they were in a relationship with a young teenage boy, to then find out this was actually a female.

“For some of these girls it was their first relationship... She’s duped them the whole time,” she continued.

“A lot of these victims are young, quite innocent. They have been completely taken in by Gemma Watts. They all believed they were in a relationship with a male.”

Investigators have identified a total of seven victims, some of whom did not want to give a statement.

But DC Kenwright said: “I think there will be further victims, who were in a relationship with Watts, who will now realise she is a woman.

“I think there could be 20 to 50,” she continued.

“I think she had been grooming other young victims online using social media profiles, which are very believable.”

Watts first came to the attention of Hampshire police in March 2018 after a doctor raised concerns a girl was in a relationship with an older boy.

The Met got involved in July that year after the defendant admitted she had been sexually active as Jake with the first three victims.

She was released under investigation by the South East force but arrested again in October 2018 by BTP officers, who found her with the fourth girl, from the West Midlands, after the victim was reported missing by her parents.

Officers had initially believed Watts was 16-year-old Jake and were taking her home to London before making the link.

Scotland Yard secured a civil Sexual Risk Order in November 2018, in a bid to protect the public, which Watts breached just two weeks later.

She was held on remand after being arrested for sexual assault in March last year but was free again in August when she was acquitted.

Watts was finally charged in September and pleaded guilty to seven offences in November, which include: Assault by penetration, sexual assault and grooming against 14-year-old girl from Hampshire; sexual assault and grooming against a 15-year-old girl from Surrey; grooming a 15-year-old girl from Plymouth; sexual assault against a 15-year-old girl from the West Midlands.
