An Essex man who subjected young children to “horrendous and sickening sexual crimes” has been jailed for more than 10 years.

Adam Austin-Andrew, 38 and from Harwich, admitted numerous child sex offences at Chelmsford Crown Court on Thursday.

Essex Police arrested Austin-Andrew in March in connection with recent offences involving children aged under 13.

Following his arrest, officers received details of historic sexual abuse, dating back to the 1990s, on a child who was aged under 13 at the time.

Investigating officer Dc Vicky Blackmore, of Essex Police’s child abuse investigations team, said: “Austin-Andrew subjected young children to horrendous and sickening sexual crimes, which will have a life-long impact on them.

“I would like to praise the victims and their families for their courage throughout our investigation and subsequent court case.

“Austin-Andrew is a dangerous abuser and has received a lengthy prison sentence. I hope this outcome offers some justice to his victims.”

Austin-Andrew admitted one count of engaging in sexual activity in front of a child, two counts of indecent assault, two counts of causing a child to watch a sexual act, five counts of sexual assault on a child and two counts of taking indecent images of children.

He was jailed for 10 years and nine months.

An NSPCC spokeswoman said: “Offenders like Austin-Andrew pose a serious risk to children and it is right that he is now behind bars for the vile abuse he has perpetuated over the years.

“It’s vital that all victims of sexual abuse know it is never their fault and are fully supported when they come forward and report it – the survivors in this case must be commended for their extraordinary bravery in speaking out against their attacker.

“We want young people to be able to recognise and report abuse, which is why the NSPCC visited 194 schools in Essex last year with our Speak Out Stay Safe assemblies and workshops.”
