A former maths teacher who used fake images of himself as a child to groom victims online has been sentenced to a further 25 years in prison, with an extended licence period of eight years. Syed Shahreear Ahmed, 37, of Mossford Lane, Barkingside, London, appeared at Southwark Crown Court on 10 July, where he was found guilty following a second trial.
Ahmed was already serving a jail sentence for child sex abuse offences when the latest convictions were secured. The sentence was handed down on Thursday, 5 November.
Investigation uncovers 12 further victims
The new convictions follow an investigation by detectives from the Met's Online Child Sexual Abuse and Exploitation (OCSAE) team. Officers uncovered 12 further victims and offences hidden within hundreds of gigabytes of digital evidence seized from Ahmed's mobile phones.
Police believe there may be even more victims and are urging anyone who had contact with Ahmed to come forward. Ahmed used fake online identities on popular social media apps with altered photographs to groom girls aged between 13 and 16 before arranging meetings and sexually abusing them.
He was convicted of 37 child sexual abuse offences, including rape, sexual assault, sexual communication with a child, meeting a child following sexual grooming, child sexual exploitation and offences relating to indecent images of children. These convictions followed an earlier trial in 2025, where he was found guilty of 14 child sexual abuse offences, alongside previous guilty pleas for offences relating to indecent images of children.
Total of 56 offences against 18 victims
In total, Ahmed has now been convicted of 56 child sexual abuse offences, relating to 18 victims. Detective Chief Inspector Brian Kelleher, from the Met's Specialist Crime Command, said: "Many offenders may believe that once they have been convicted our work stops. This case shows that is simply not true."
Following Ahmed's initial conviction, detectives continued to scrutinise digital evidence, pursuing every line of enquiry and identifying further victims who had been targeted, groomed and abused. Kelleher added: "Ahmed was a manipulative and prolific sexual predator who spent years creating fake online personas to gain the trust of children before exploiting them. This case is a stark reminder to parents that people online may not always be who they claim to be."
He urged parents to talk openly with their children about who they are communicating with online and to encourage them to speak to someone they trust if an interaction makes them feel uncomfortable or concerned.
Offending dating back to 2019
During the first trial, the court heard how Ahmed's offending first came to light in May 2023 after two teenage girls independently reported concerns to police. One 14-year-old girl jumped from Ahmed's moving car after becoming terrified by his behaviour. Her report, alongside information from another victim, led officers to begin piecing together a pattern of offending that stretched across multiple counties.
Detectives subsequently examined digital material recovered from two mobile phones seized following Ahmed's arrest. Officers spent months reviewing hours of social media messages, images and videos, eventually identifying seven victims and uncovering offending dating back to 2019. The Met took over the investigation due to the complexity of the case and the geographical spread of victims, working with police colleagues from Cambridgeshire, Thames Valley, Hertfordshire, Essex and Kent.
Detective Constable Carl Conibeere said: "Protecting children from sexual abuse and exploitation remains one of our highest priorities. We will continue to relentlessly pursue offenders, identify those who may be at risk and ensure victims receive the support they deserve. Our determination to secure justice does not end with a conviction."
Prosecutor highlights teacher's betrayal
Claire Brinton, Specialist Prosecutor for the Crown Prosecution Service, said: "Syed Ahmed pretended to be a teenage boy to target his young victims via social media platforms, where he groomed and exploited them for his sexual gratification."
Some of his sexual abuse took place online, but he also arranged to meet some of his victims so that he could commit further sexual offences, including rape. All of his victims were under 18 years of age, some as young as 14. Brinton added: "His predatory behaviour is all the more shocking because he was a teacher who had been trained in safeguarding children."
She said the sentence sends a clear message that the CPS will pursue justice and prosecute those who sexually exploit children both in person and online. She encouraged any victims of child sexual abuse and sexual violence to report the crimes committed against them to the police.
Appeal for further victims
Detectives continue to appeal for anyone who may have had contact with Ahmed, or who believes they may have been affected by his offending, to contact police. Reports can be made online or via 101. In an emergency, always call 999.
