A groom raped and robbed a woman in a "sustained and systematic" attack in a park before marrying his pregnant fiancee hours later. 

Convicted rapist Derry McCann, 28, attacked the woman as she walked back from an art exhibition through a popular east London park in the early hours of the morning. 

He had recently been released from a life sentence given to him in 2006 when he was 17 for a near identical attack on a trainee solicitor. 

He was arrested after the 24-year-old reported the assault as she walked home through Victoria Park in Hackney following a night out with friends in the early hours of January 13. 

She told police her attacker had grabbed her and demanded cash before dragging her into bushes and raping her, and then stealing her bra and mobile phone. 

McCann married his pregnant wife on the same day of the alleged attack in a ceremony at The Vestry in Bromley-by-Bow, East London. 

It is understood he attacked the victim shortly after he was released from a life sentence for raping a trainee solicitor when he was 17 years-old and on a electronic tag for burglary in 2006. 

At Inner London Crown Court he was convicted of six counts of rape and robbery after dragging his victim into a secluded area of an East London park. 

Today he appeared at Snaresbrook Crown Court charged with three counts of rape, one count of assault by penetration and one count of robbery. 

Wearing a grey track suit he spoke to confirm his name and plead guilty to all the offences. 

Prosecutor Kate Bex QC said: "It was about midnight or just after and the victim was walking a short distance home after being out to an art gallery with friends. 

"She was almost within sight of her own front door when she skirted round the side of the park on her usual route home, avoiding walking through the middle of the park because that was too dangerous. 

"She went round the side and it was when she was near the exit of the park the defendant grabbed her arm and pulled her to one side and a sustained and systematic attack and the result are the offences which are in the indictment. 

"It was penetration in every orifice accompanied with unusual conversation with the victim, best described as mind games in an attempt to control her. 

"He asked her what she thought he was going to do with her before carrying out the act. 

"He behaved oddly in other respects. In interacting with the victim concerning the condom when he penetrated and ejaculated. 

"Items of her property are listed in the robbery. There was he theft of her mobile phone and a piece of her underwear." 

The prosecution revealed he had recently been released from prison and said: "The oldest conviction on his record might also be of some relevance as the circumstances are very similar." 

Edmund Vickers QC for the defence said, a "life sentence was inevitable in this case" and asked for mental health reports. 

At a previous hearing prosecutor Janine Sheff said: "This is a rape allegation. A very serious allegation. 

"A stranger rape in a park. A rape in every orifice in effect, on the defendant's wedding day." 

Today Judge Martyn Zeidman QC, the honorary recorder of Redbridge, said: "You have done the most terrible things and you will be going to prison, as you understand, for a very very long time. 

"The sentencing is set for Friday the 28 April." 

McCann, from Hackney, east London, was remanded in custody until his sentence later this month.
