A second man has been charged by police investigating the murder of a Syrian-born imam in north London.
Abdulhadi Arwani, 48, an outspoken critic of Syria’s President Bashar Al Assad, was shot dead earlier this month.
His body was found in his car in Wembley on 7 April.
Scotland Yard said Khalid Rashad, 61, from Wembley, has been charged with possession of an explosive substance for an unlawful purpose.
He is also accused of possession of ammunition for a firearm without a certificate.
Rashad has been remanded in custody to appear at Camberwell Green Magistrates’ Court on Saturday.
It comes after Leslie Cooper, 36, from Brent in northwest London, appeared at the Old Bailey last week charged with Mr Arwani’s murder.
