A SERIAL sex attacker who was caught trying to rape a woman in the street is facing an indefinite sentence.

Charles Gregory, 24, of Offord Road, Barnsbury, preyed on two drunken women in separate sex attacks in Islington.

He lured his first victim, a 17-year-old girl, to his home where he pinned her down and gagged her to stifle her screams as he forced her to have sex.

Just a fortnight later he tried to rape a 31-year-old and stole her mobile phone, Blackfriars Crown Court heard.

Last year a jury convicted him of the attack on the older victim and in a separate trial which ended yesterday he was found guilty of raping the teenager.

She told how on January 30, 2010, she had gone back to Gregory’s home in Offord Road with mutual friends after downing a bottle of wine.

The youngster then continued to drink brandy and coke and the defendant, who she said seemed nice at that time, kissed her.

The alcohol then started to make her feel unwell and she went to the bathroom.

She turned round to find Gregory standing behind her in the bathroom having dropped his trousers and boxer shorts.

He locked the door, switched off the light and demanded: “Come here”.

The shocked victim refused, begging: “Get off me”.

But he ignored her pleas, threw her to the floor, pinned down her arms and legs and raped her.

When she screamed in agony he stuffed a cloth into her mouth.

But she did not raise the alarm with police for a fortnight, and the day after that he was to strike again.

He found the 31-year-old victim drunk in nearby Copenhagen Street on February 13 and tried to force his penis into her mouth and rape her vaginally.

Gregory managed to steal her mobile but witnesses came to her aid and he was arrested.

He was found guilty of the earlier attack by a majority of 10-2 by jurors who had not been told about his previous convictions.

They then heard about his shocking record of attempted rape and a string of theft charges spanning a decade.

Turning to the jury, Judge Aidan Marron QC told jurors, many of whom appeared alarmed: “Don’t think things have been kept from you.

“It is important people get a fair trial and it was my judgment in this particular case and in the other case, that the matters should be kept quite separate, that a jury should not be told, because fairness would be compromised.

“Having heard both trials my personal view is this defendant is a danger to women.”

The judge ordered probation reports and remanded Gregory in custody ahead of sentence on March 23.

The court heard the defendant has a “very low IQ” after a car crash when he was aged 16 put him in a month-long coma.

He showed no reaction to the verdict.

Gregory, denied rape, two counts of attempted rape and theft.
