A builder who repeatedly attacked a toddler in a horrifying campaign of rape has been jailed.

Bradley Martin, 29, raped the three-year-old on multiple occasions, a court heard.

The monster even attacked as an older boy watched.

Martin of Bexhill, East Sussex, searched online for ways to cover up his crimes, a jury heard.

Search history showed he looked for ideas on how to get rid of DNA evidence and 'how long does it take to get DNA results in a criminal case UK'.

He also searched; 'when can a DNA test be wrong'.

The abuser even tried to work out how long he would spend in prison.

Martin searched: 'How much time do sex offenders spend in jail'.

Rachel Beckett for the Crown told the jury at Hove it is understood the older boy might have been present during one or more of the rapes.

Martin also tried to blame the older boy for the injuries he inflicted.

"In all of the circumstances, the Crown submits that the offending could be considered a campaign of rape."

Martin raped his victim multiple times.

His campaign of rape was only stopped by hospital staff who alerted police after the mother found unexplained injuries.

Police found 127 illegal images of extreme pornography involving both animals and humans on his phone.

Martin was found guilty of three counts of rape of a child under 13.

He was sentenced to 23 years in prison, with an eight-year extended licence.

Detective Constable Kelly Yates, of Hastings’ safeguarding investigations unit, said: “Bradley Martin abused his young victim in the most heinous way, uncovered thanks to the care of the child’s mother and diligence of medical professionals.

“My thanks go to the victim and his family for their courage and determination through what has been an extremely difficult process.

“With their support we have been able to put Martin behind bars for a significant amount of time and put steps in place to ensure he can cause no further harm to the public.”

Martin will be on the Sex Offenders’ Register for life and was given an indefinite Sexual Harm Prevention Order significantly restricting his access to children and digital devices.
