Terrifying CCTV shows man who raped stranger hours before his wedding stalking woman who escaped before grabbing victim

In the footage, Derry McCann grabs his victim only three minutes after he was seen running after an earlier target who got away

Terrifying CCTV has shown a man who raped a stranger hours before his wedding stalking a woman who got away - before finally grabbing his victim minutes later.
Metropolitan Police tonight released the chilling footage of Derry McCann, 28, who launched his horrific two-hour assault hours before he wed his pregnant fiancée.
In the first part of the clip, McCann is seen loitering in a hoodie on a street near a park in east London at midnight on January 13.
By 12.01am, he has spotted a woman who walks by and begins to follow her, walking faster as she walks down the street.
He crosses the road to her side of the street and McCann begins running after her. The woman gets away.

By 12.04am, however, the footage shows that McCann has found another woman, who he grabbed and dragged into the undergrowth in the park.
He is shown exiting the park two hours later at 2.02am.
The groom-to-be has been jailed for life with nine years minimum - a decade after he was jailed over another parkland rape.
On March 2, at Snaresbrook Crown Court, McCann pleaded guilty to three counts of rape, one count of sexual assault by penetration and one count of robbery.
He played "mind games" and taunted the woman by asking what she thought he would do next, Snaresbrook Crown Court was told.

Hours later, he tied the knot with his girlfriend in a ceremony at The Vestry in Bromley-by-Bow, prosecutors said.
Today, the court heard how McCann stalked another woman before attacking his eventual victim.
He is currently on suicide watch at HMP Belmarsh after trying to kill himself ahead of today's sentencing.
His conviction comes a decade after a teenage McCann was jailed for carrying out a prolonged rape attack.
McCann had been released in December 2015 after serving less than nine years of a life sentence imposed in 2006 when he was 17 for a near identical attack on a trainee solicitor.
Today he was handed three concurrent life sentences today with a minimum of nine years - the same minimum term he received in 2006.

Judge Martyn Zeidman QC, the honorary recorder of Redbridge, said: "Friday the 13th of January 2017 is a date that your victim will never forget.
"You behaved as a monster. Raping this victim in every possible way and doing it in a manner that amounted to torture.
"Playing mind games, asking what she was going to do next, and taunting her for almost two hours.
"In addition to the physical pain, you set out to degrade and humiliate her in ways that are so cruel and gross that I will not identify them any further.
"Let me be blunt: I am worried you might even relish a recital of them.
"As the brave victim said in her statement, 'I thought that rape was when you get dragged into the bushes and they have sex with you.

"But this was a long, drawn out psychological game that was being played. And I just never knew what was going to make him angry'."
The Judge added: "And then amazingly, just hours later you married your pregnant girlfriend.
"I am not asking for a response, but I just wonder what sentence you would impose if someone had done this to your wife or a female friend of yours.
"This wrongdoing, in this case, is made even worse by the serious violence that you have carried out before."

McCann grabbed the victim and demanded cash before dragging her into bushes and raping her.
After the two-hour ordeal, he took pictures of his victim and said she was lucky he had not filmed it, before stealing her bra and mobile phone and fleeing.
McCann was identified as a suspect because the "modus operandi" was so similar to the 2006 attack.
Kate Bex QC, prosecuting, said he carried out "a sustained and systematic attack", and played "mind games in an attempt to control her".
She said: ""He kept coming back to the question, 'do you think I am going to rape you?'
"At one point he said 'I am going to smash your skull on that tree if you don't do what you are told'.
"She described him as clearly wanting to feel superior.
"She described a heavy emphasis on trying to get into her head.
"She was afraid he was going to kill her."

CCTV showed him following another woman in the park at about 12.01am, who escaped, before he grabbed his victim at 12.04am.
The prosecutor added: "Mr McCann was identified as a suspect as a result of the very distinctive modus operandi, the striking similarities, for an offence for which he had recently been released from prison."
He was released from jail on December 14 2015, and moved in with family in Hackney.
McCann secured work as a trainee roofer, and met his partner who fell pregnant last July.
He kept in touch with his probation officer, and took part in a community-based follow up to the sex offenders' treatment programme, attending two sessions before the attack.
Edmund Vickers QC, defending, said McCann had been diagnosed with a personality disorder, but it was "not sufficient" enough to warrant a hospital order.

McCann had tried to kill himself in Belmarsh jail, and is currently on suicide watch, the court heard.
Wearing a prison issue grey tracksuit and sporting a bushy beard, McCann made no reaction as he was sentenced.
In 2006, McCann was convicted at Inner London Crown Court of six counts of rape and robbery after dragging a 30-year-old victim into a secluded area of Mile End park in east London.
Then 17, he mugged the victim with a pal, who left after McCann said: "I'm going to have fun with this one, then I'm going to kill her."
During the prolonged assault he told her she was his girlfriend and he wanted her to have his child before saying he was going to chain her up in his basement where he kept other women.
He told her that his friend would come back and stab her to death if she resisted.
Judge Lindsay Burn handed McCann a life sentence, with a minimum of nine years before he could be released on parole.
