Reports have emerged that the Libyan army has arrested Abu Sufian Bin Qumu, a leader of an Islamist militia group and former driver of Osama Bin Laden.

He was reportedly captured in raids in 'one of the last strongholds' of extremist groups in Derna.

Bin Qumu had purported links to attacks in Benghazi that killed US diplomat Chris Stevens in 2012.

Abu Sufian Bin Qumu has reportedly been captured in Libya where he established Islamist faction Ansar al-Sharia

It is believed Bin Qumu was arrested after his group ran out of ammunition at a hideout in Derna, according to Al Arabiya.

The 59-year-old is considered a high-ranking operative of al-Qaeda based on his associations with the terrorist group around the time it was founded.

He was said to be the personal driver to Osama Bin Laden in Sudan where the al-Qaeda leader lived for three years during the 1990s. But Bin Qumu denies this.

Washington Post reported he fought alongside the Taliban against US forces in Afghanistan before he was detained at Guantanamo Bay after being captured in Pakistan.

The US military characterised him as a 'medium to high' risk to national security while he was in US custody and he refused to cooperate with authorities and explain his past associations with Islamic extremists.

Bin Qumu was suggested to be involved with the armed attack on the US Consulate in the Libyan city of Benghazi on September 11, 2012

He was extradited to Libya in 2007 where he served jail time before being released by Muammar Gaddafi.

Bin Qama returned to Derna to establish the Ansar al-Sharia extremist group, who advocate the implementation of Sharia law across Syria.

It was also suggested by Washington Post that the Islamic faction's militiamen were present during the Benghazi attacks in 2012.

Last year, Ahmed Abu Khattala was on trial in the US capital as the suspected mastermind of the attacks on a diplomatic compound in the Libyan city that killed four Americans.

It resulted in the death of Chris Stevens — the first US Ambassador killed by violence overseas since 1979.

Al Arabiya said Bin Qama, despite being a leader of Ansar al-Sharia, no longer played a prominent role in the group.

He is set to be questioned by the Libyan National Army according to reports.
