Matthew Falder

Matthew Alexander Falder (born 24 October 1988) is an English convicted serial sex offender and blackmailer.

Falder's offences date back as far as 2007, where he engaged in voyeurism by secretly filming his university housemates in their shared bathroom.

He would later inform a housemate about his offending, which she laughed off at the time.

From a period of time between 2009 and 2017, he coerced his victims online into sending him degrading images of themselves or into committing crimes against a third person such as rape or assault.

He managed this by making threats to the victim by saying he would send their family or friends degrading information or revealing pictures of them (which he usually obtained earlier by obtaining a false trust with the victim) if they did not comply with his commands.

Falder hid behind anonymous accounts on the web and then re-posted the images to gain a higher status on the dark web.

Investigators said that he "revelled" in getting images to share on hurtcore websites.

The National Crime Agency (NCA), described him as "one of the most prolific and depraved offenders they had ever encountered."

Falder pleaded guilty to 137 charges from 46 complainants, making him one of the UK's most prolific convicted sex offenders.

Falder's online offending was detected as early as 2009.

Falder would usually pose as a young woman online and manipulated young children to photograph themselves in compromising positions and then offered the images over the internet.

In April 2015, the NCA discovered someone posting to the hurtcore websites under the name "666devil", who later turned out to be Falder.

NCA officers arrested Falder in his office at his place of work on 21 June 2017.

When they read out a list of the offences he was suspected of committing, Falder remarked that it sounded "like the rap sheet from hell".

Falder's victims numbered over 50, and it took over 30 minutes to read out the charges to him at Birmingham Crown Court.

Originally charged with 188 offences, he pleaded not guilty to 51 of them; the prosecution accepted this, but they were ordered to remain on file.

Falder used various accounts on several websites to pose as a young girl or woman named 'Liz'.

On the dark web Falder used names such as 'inthegarden', '666devil' and 'evilmind'.

Falder had seventy different online identities.

He lured people into taking photographs of themselves in humiliating situations.

He blackmailed one person into raping a four-year-old child.

Falder engaged in hurtcore, which police have characterised as manipulating others into performing acts of "rape, murder, sadism, torture, paedophilia, blackmail, humiliation and degradation".

One of Falder's victims was just 14 years old; Falder said online he would willingly "mentally fuck her up" and added, "I am not sure I care if she lives or dies."

Falder increased the pressure on his victims, at least four of whom attempted suicide.

When one of his victims pleaded for the abuse to end or else they would kill themselves, Falder replied that the images he already had on them would be circulated on the Internet anyway.

Falder maintained he could not be caught and said he did not care if the victims lived or died.

In addition to the National Crime Agency (NCA), the investigation to uncover his identity involved GCHQ, US Homeland Security, Europol, Australian Federal Police, New Zealand Police, and the Israel Police; it lasted four years.

Will Kerr of the NCA felt tech companies gave less than ideal cooperation with the police during the enquiry.

Kerr maintained accounts were closed down possibly preventing police identifying other victims and identifying patterns of offending.

Kerr feared this may have delayed identifying offenders and wanted government action to make tech companies cooperate better in future.

The NCA detailed crimes such as blackmailing people into eating faeces, licking toilet seats and tampons and persuading people to eat dog food.

They described him as "one of the most prolific and depraved offenders they had ever encountered".

On 16 October 2017, Falder pleaded guilty to 137 offences against 46 victims, making him one of the most prolific sex offenders in British history.

In February 2018 he was jailed for 32 years and ordered to serve a further six years on extended licence.

The Court of Appeal later reduced the term of imprisonment to 25 years, with an extended licence of 8 years.

Falder grew up in an upper middle class family in Knutsford, Cheshire.

He attended Kings School in Macclesfield, Cheshire, where it was reported that he had "excelled".

After school he attended Clare College of the University of Cambridge, specialising in seismic oceanography and earning masters and doctoral degrees.

At the time of his arrest, he was working as a post-doctoral researcher and lecturer in geophysics at the University of Birmingham.

Falder was well-liked in his peer group, and was described as being extroverted, funny and larger than life.
