A psychic who conned young female disciples into stripping off for raunchy spiritualist sessions is facing jail.

Karl Lang, 49, was found guilty on Friday of 12 counts of causing women to engage in sexual activity without consent.

The rogue medium targeted two women in their 20s who sought him out in the belief he could contact dead relatives.

Lang, of Newport, South Wales, brainwashed his vulnerable victims and went so far as to claim he was Jesus Christ reincarnated.

Both women were encouraged to perform sex acts in front of him and pressed to act more and more outrageously as his influence increased.

One told the trial she was conned into acting like a "porn star" in the belief that her naked antics would boost her own spiritual powers.

Lang generally sat watching, fully clothed, but would occasionally strip off himself and join in.

His manipulative behaviour lasted almost four years and covered a period from November 2005 until September 2009.

A jury at Newport Crown Court found him guilty of all 12 charges, dismissing claims that he was an innocent spiritualist instructor.

All 12 counts were majority verdicts. The brief trial started on Monday.

Judge Patrick Curran QC agreed to grant Lang bail to "get his affairs in order" until a sentencing hearing some time next month.

But he warned: "This involved a very serious breach of trust and an immediate custodial sentence is, it seems to me, absolutely inevitable."

He described Lang's activity as "systematic conduct and a breach of trust involving two very vulnerable young women".

He added that they were "vulnerable in the sense that they were bereaved and sought the defendant's consultation in communicating with those who died, and he took the most gross advantage of the situation".

Lang stood ashen-faced and shook his head in apparent disagreement as each guilty verdict was delivered in court.

After his release on conditional bail, he left the courtroom with friends, still shaking his head as if the outcome was unbelievable.

The jury agreed he was essentially a predator who targeted vulnerable women who turned to him with hope while at their lowest ebb.

He operated by offering his victims spiritual training as mediums, claiming it would boost their own psychic powers.

Once under his spell they were manipulated into stripping off and effectively acting out raunchy sex shows for his private gratification.

Both young women were also encouraged to take naked photographs of themselves and send them to his phone.

Lang vehemently denied such claims, dismissing them during the trial as "wicked lies".

He claimed he had been shocked when one young woman stripped off during a spiritualist session.

In interview he told police that "letting go" was key to success in spiritualism and if that is what they wanted to do "it was their problem".

He told the jury he could see, hear and communicate with spirits from the other side, and had done so since the age of four.

He also claimed he had sought out a spiritualist church in Newport after a spirit attacked him at home in 1999.

From then on, he claimed, his powers increased and he performed to crowds of up to 1,000 at spiritualist churches across the UK.

Despite his insight into the world of the departed, the outcome of his trial today shows he failed to foresee where his behaviour would ultimately lead.

David Watts, senior crown prosecutor for the Crown Prosecution Service in Wales, said: "This was a very unusual case involving the cynical exploitation of a number of young women.

"Karl Lang preyed on his victims in a callous and underhand manner. He targeted them at times in their lives when they were at their most vulnerable.

"Each of Lang's victims has shown tremendous courage in coming forward and reporting what happened to them. We hope that today's verdict will provide them with some measure of comfort."
