Shabazz Suleman, 21, was recruited through Twitter by ISIS and went to Syria to join them

He claimed he spent his time avoiding violence and playing games instead

He underwent weapons training and was a guard but denies fighting

He said he takes responsibility for joining a terrorist organization but wants to return to Britain

A young Brit who fled to Syria to fight for ISIS has revealed he spent most of his three years in Raqqa playing PlayStation and riding his bike.

Shabazz Suleman joined ISIS in 2014 and claimed he didn't kill anyone but is now desperate to return to the U.K. to face justice.

The High Wycombe grammar schoolboy, 22, insisted his intentions were good when he fled the country to fight the Assad regime. It never materialized and he ended up fighting alongside the barbaric ISIS terrorists.

He was issued with an AK-47 and a uniform but says he spent his time in hiding trying to avoid conflict as his comrades butchered innocent people.

Suleman dodged fighting by going from house to house playing Grant Theft Auto and Metal Gear Solid on his PlayStation and riding around Raqqa on his bike.

He even passed corpses on an infamous roundabout in the city, used specifically to crucify ISIS prisoners.

On the weekend his father warned about the dangers of being 'brainwashed' through the internet - and that he feels sympathy for those who join the death cult.

His father Afzal Suleman, 46, said he regretted buying a phone for his son who he claims was radicalized on Twitter.

Suleman went missing on a family holiday to Turkey three years ago where he sneaked across the border to Syria.

After receiving weapons training, he claims he was sent to the Iraqi border as a front-line fighter, but avoided firing his Kalashnikov at all.

When he returned, he asked to quit ISIS, which landed him in a prison set up under a stadium in the center of Raqqa.

He said after a month of watching people get tortured, he agreed to stay with the terror group, taking a job with the military police - a branch set up to keep public order.

But, again, he insisted he spent his days playing games and sitting in an office.

"I take responsibility. I was with ISIS, I was with a terrorist organization. But I didn't kill anyone, I hope I didn't oppress anyone," he told Sky News.

He claims that he has renounced its twisted doctrine and wants to return to Britain.

He was held by the Turkish secret service before being exchanged with 180 others for 49 Turkish hostages captured at the embassy in Mosul, northern Iraq.

Suleman's father said that he had intermittent contact with his son during the three years and he believed that Suleman had not killed or tortured anyone.

"If he has seen that side of things he wouldn't have joined them. He was thinking of going there and helping people." He said that his son always had a keen interest in politics but that he had increasingly spent time alone in his room on his mobile phone.

Via encrypted messages he said he went through 'intense' indoctrination by the group, adding: "I never thought I was being brainwashed until I saw the way they treat other Sunnis."

Around 850 U.K.-linked individuals "of national security concern" made the journey to engage with the conflict in Syria, with just under half of those believed to have come back.

The figure of approximately 425 returnees is the fourth highest for individual nations in an analysis published by the Soufan Centre and the Global Strategy Network.
