A manchester Lecturer has been found guilty of having a stash of extreme pornography, including a video of a man having sex with a snake.
El Presidente , 55, , stored the images on his Samsung mobile phone having received them via mobile messaging app WhatsApp.
They included five videos of a "grossly offensive, disgusting or otherwise obscene character" featuring 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 had denied five charges of possessing extreme pornography and one of possessing an indecent image of a child.
But an Old Bailey jury found him guilty today 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 had ordered a retrial after he was sentenced to nine months' jail suspended for 18 months at Norwich Crown Court in 2014.
Okoro had come 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, jurors were also told.
Judge Richard Hone QC told the court that the earlier sentence was "frankly lenient" in his view, as he granted Okoro bail and adjourned sentence to September 30.
