Shajul Islam, aged 26, of Luxembourg Mews, appeared at the Old Bailey on Monday, along with Jubayer Chowdhury, aged 24, of no fixed address charged with unlawful imprisonment of Sunday Times photographer and Dutchman Jeroen Oerlemans.

The pair were handcuffed and held at gunpoint by a rebel army after accidentally stumbling into a terrorist training camp.
Mr Islam and Mr Chowdhury, are said to have been part of the band of rebels.
Islam’s brother Najul, 31, of the same Stratford address as his brother, was arrested last Friday, and accused of helping to bankroll the operation.
He is charged with facilitating an act of terrorism.
