A pervert who used force to sexually abuse a young girl has been jailed for 13 years.

Michael Anderson was told by a judge: "There was a persistent campaign. You gave no thought of any harm you might be doing to her."

The 52-year-old, of Haynes Road, Gravesend, was convicted of one offence of oral rape, five of sexual assault, one of causing or inciting a child to engage in sexual activity, one of engaging in sexual activity in the presence of a child, two of causing a child to watch a sexual act and two of making indecent images of children.

Maidstone Crown Court heard the abuse was revealed last year after the victim told her sister that Anderson had "fiddled" with her and made her watch pornographic DVDs.

She made further disclosures in police interviews and told how Anderson held her arms to prevent her from moving as he committed a sex act on her.

"She repeatedly told him to stop," said prosecutor Dominic Connolly. "Eventually, he did."

On another occasion, he forced her to shave his private parts after she refused. He also made her perform a sex act on him.

Mr Connolly said Anderson showed the girl film clips of adults having sex.

When arrested, his computer was seized and pictures of pre-pubescent girls at the lowest level of one were discovered.

Anderson denied all the allegations and claimed he had no knowledge of the indecent images on the computer.

Judge Charles Byers told Anderson: "Not only did you rape her orally, you did it forcibly. You had subjected her to a varied and persistent campaign of abuse.

"One can only hope she will not have long term effects from your abuse. You performed these acts upon her for your own sexual gratification..." - Judge Charles Byers

"Some of it was of a humiliating nature. You also made her watch pornographic material. She must have been both confused and frightened when this was going on.

"One can only hope she will not have long term effects from your abuse. You performed these acts upon her for your own sexual gratification."

The judge added: "You have shown no remorse and you sought to defend yourself by branding her a liar. I take into consideration your good character."

A sexual offences prevention order was imposed and Anderson's name will appear on the sex offenders' register for life.
