A disgraced south London doctor has walked free from court after being convicted for a second time of having a stash of "extreme" pornography, including a video of a man having sex with a snake.

GP Cyprian Okoro, 55, "betrayed" the high standards of his profession and was lucky not to have been jailed over his collection of obscene videos sent to him via WhatsApp, a judge said.

Following a retrial ordered by the Court of Appeal, the doctor was handed six months in custody suspended for 12 months and ordered to re-sign the sex offenders' register.

The court had heard how Okoro had five videos of a "grossly offensive, disgusting or otherwise obscene character" on his Samsung phone.

They featured women having sex with dogs, a man having sex with a snake and a woman having sex with a horse, the court heard.

Okoro also had an indecent video of a two-year-old boy, which was among images moved from his photo gallery into a password-protected "vault" app on his phone.

The defendant, of Cameron Place, Streatham, denied five charges of possessing extreme pornography and one of possessing an indecent image of a child.

Earlier this month, a jury at the Old Bailey found him guilty of all but two charges of possessing extreme pornography relating to bestiality with dogs.

Following the verdict, the jury was told that it was the second time Okoro had been convicted in what the judge described as a "quite unusual case".

The Court of Appeal ordered a retrial after he was sentenced to nine months' jail suspended for 18 months at Norwich Crown Court in 2014.

He had also been ordered to sign the sex offenders' register for 10 years, complete an internet sex offenders' programme, do 200 hours of unpaid work and be subject to 18 months of supervision.

The court also heard how in April 2000, Okoro was found guilty by a General Medical Council panel of serious professional misconduct relating to "inappropriate comments of a sexual nature" at work.

He was suspended for 18 months, extended for a further 12 months in 2001, the court was told.

Okoro came to the attention of police after a woman made an allegation of sexual assault against him, but no further action was taken over the claim.

In mitigation, Stephen Akinsanya said it was "regrettable" that such a man had lost his good character and possibly his career.

He told the court: "His biggest regret is he did not delete the material the moment it arrived and did not seek to cut off the ties with those who sent the material to him."

Mr Akinsanya said it was through "reckless stupidity" he had risked his whole career and it was unlikely Okoro would be able to work in the UK again.

He said the GP had been "traumatised" by the stigma attached to his conviction but insisted he was not a paedophile.

He had never posed a danger to his own children or those he interacted with through his work, the court heard.

Sentencing, Judge Richard Hone QC told Okoro: "You have betrayed the high standards of conduct required by your profession."

The judge said he had to allow for the fact the defendant had completed the unpaid work, supervision requirement and most of the sex offenders' programme.

Although he was "constrained" by the earlier sentence, he echoed the appeal court judge by saying Okoro had been "fortunate" he had not been sent immediately to prison before.

Okoro qualified as a doctor in Lagos, Nigeria, in 1986, and received an interim suspension by the General Medical Council in September 2013.
