Three people who kidnapped a woman and subjected her to horrific attacks for almost three hours, have been jailed.

The vicious kidnappers seized the woman in Chatham, where they bundled her into a car and drove to a secluded London park.

There, they assaulted her with a metal baseball bat, knuckleduster and dog chain. At one stage a sock was stuffed into her mouth to stifle her screams. The ordeal lasted two hours and 45 minutes.

The thugs also threatened to kill members of her family before dumping her out of a car on Friday, April 1 this year.

Today, Kaswayne Williams, now 20, of Peckham Park Road, Peckham, was handed an extended sentence of 20 years for the brutal attack. He was jailed for 16 years with another four years on licence. He will have to serve at least two thirds of his sentence before he is eligible for parole.

George Emmett, now 19, of Lakeside Close, Sidcup was handed eight years in jail, while Sheneqwa Delpratt, 20, of New Paragon Walk, Walworth was locked up for five years.

A victim impact statement was read out during sentencing at Maidstone Crown Court today. The court heard how the victim will never be able to forget what happened and that she is constantly looking over her shoulder.

Months on, she still suffers from loss of feeling in her leg and chronic back pain which needs regularly physiotherapy. Her left arm is still swollen and tender, and she has scaring from the blows by the baseball bat.

As well as the physical injuries, she suffers from anxiety, panic attacks, has been unable to sleep because of flashbacks, and has been diagnosed with PTSD.

Sentencing the trio, Judge Julian Smith said the attack was intended to punish the victim for refusing to pay the debt owed to Williams.

Describing the attack as “considered and carefully planned”, he said Williams knew the victim would not meet up with him and would not take his calls, so he recruited Emmett – a friend of the victim – to lure her to a meeting.

He said: “She was walking into a trap created by the three of you. You took her away from her home, to where she was a stranger, completely isolated and didn’t know the area.”

Speaking to Emmett, Judge Smith said: “It’s pretty clear you knew what was to happen. I’m satisfied that you know why this was being done.

“You demonstrated total contempt by assault her before leaving her to Williams. You betrayed her trust.”

Addressing Delpratt, he said: “You were within mere inches of all that was happening. She pleaded with you to help her and release her. You ignored her. You moved the car from the place where you dropped them to the other entrance [of the park].”

The trio were convicted following an investigation by the Kent and Essex Serious Crime Directorate.

Last month a jury returned guilty verdicts after a two-week trial at Maidstone Crown Court. All three were found guilty of kidnap.

Williams was also convicted of attempting to cause grievous bodily harm and possessing an imitation firearm with intent to cause fear of violence, while Emmet was found guilty of assault.

Both men were also found guilty of blackmail, robbery and possessing offensive weapons.

The court heard how the victim had arranged to meet Emmett in Hopewell Drive, Chatham, at about 11.30pm to discuss money that she owed.

As they spoke, a black Ford Focus driven by Delpratt and with Williams in the passenger seat pulled up alongside them.

After letting her dog off its lead, Emmett and Williams forced the woman into the back of the car before binding her hands with duct tape.

During the journey to London, the victim was ordered not to look out of the window and was told that she owed Williams £2,000 and that if she did not pay him then he would kill members of her family.

After some time the car stopped and Emmett punched the woman in the face before hitting her with her own dog chain.

He then walked away from the vehicle, leaving Williams and Delpratt alone with the victim.

The car was driven to an estate in south London that has since been established as Burgess Park, Southwark, where Williams threatened the woman with a firearm.

He then dragged her out of the vehicle by her hair and led her into a park area where he began to attack her with a metal baseball bat.

A sock had been stuffed into her mouth and secured with duct tape so nobody would hear her screaming.

Following the assault, she was bundled back into the car and driven to Nunhead railway station where Williams punched her twice in the face with a knuckleduster before dumping her out of the vehicle and driving away.

She was found by a member of the public who phoned for an ambulance.

Delpratt handed herself into police on Monday, April 4 while Williams was arrested the following day and Emmett on Thursday, April 14.

Investigating officer Detective Constable Matthew Lincoln said: "These are quite possibly the most callous acts of violence I have ever investigated in 15 years as a police officer.

"It is a truly shocking case in which two men viciously assaulted a woman in an argument over money, assisted by Delpratt whose role as designated driver meant she was far from being an innocent bystander.

"Neither Williams nor Emmett demonstrated any concern for their victim’s welfare and she could have very easily died after being subjected to such serious and sustained attacks. I would like to praise the tremendous courage she has displayed throughout this whole ordeal.

"Kent Police simply will not tolerate such appalling acts of violence and all three defendants are likely to receive lengthy prison sentences for the horrendous crimes they have committed."
