A schizophrenic drug user was found guilty yesterday of forcing a fellow psychiatric patient to perform oral sex on him.

Cecil Eversley Darrell, 57, was facing a jail term last night after a Supreme Court jury of nine women and three men took less than two hours to reach a unanimous guilty verdict on a charge of serious sexual assault causing bodily harm.

The attack happened on March 22, 2004, when Darrell drove his victim, who has bipolar disorder and was a patient at the Mid-Atlantic Wellness Clinic, to Devonshire Bay to smoke drugs.

She told the court this week that she walked with him to a secluded area where he demanded she perform oral sex on him before choking her.

The 42-year-old said he then put on a condom and sexually assaulted her. Darrell, who denied the charge, claimed she consented to sex.

His lawyer, Llewellyn Peniston, told the jury the woman agreed to have sex with his client in exchange for drugs but that a brown paper twist in which she believed there was ?something nice to smoke? contained only a pebble.

Puisne Judge Charles-Etta Simmons told the jury before they retired yesterday: ?Her evidence is that he demanded sex which she refused.

?She told us that she had not arranged to have sex with Mr. Darrell and that she was hurt and upset over what he did to her.?

The judge asked the jury to consider whether Darrell had tried to trick the woman into having sex. If he had, she said, the fraud cancelled out her consent.

On Monday ? the third day of the trial ? Darrell was reprimanded by Mrs. Justice Simmons after repeatedly calling out ?that?s wrong? during prosecutor Graveney Bannister?s closing remarks.

The jury had heard that day from Judith Brewster Minors, a nurse and sexual assault response expert at King Edward VII Memorial Hospital.

She examined the victim on the day of the assault and found her dishevelled, untidy, unkempt and tearful. She said she noticed that the woman had scratches and abrasions, a swollen neck and signs of forced sexual penetration.

Darrell was told to be quiet yesterday after haranguing the judge when she refused to grant him bail. Mr. Peniston had asked that his client be released pending sentence.

But Mr. Bannister opposed the application. ?He has a history of violence,? he said.

Mrs. Justice Simmons remanded Darrell in custody and adjourned sentencing until a drug and alcohol assessment plus social inquiry and psychiatric reports have been carried out.
