(BBC) A friend of the Manchester Arena bomber will be forced to answer questions at the inquiry into the atrocity or face arrest, a judge has ruled.
Ahmed Taghdi, 29, helped to buy a car which was used to store components of the bomb assembled by Salman Abedi.
Mr Taghdi, along with Salman Abedi, also visited convicted terrorist Abdalraouf Abdallah in jail.
Terror experts believe Abdallah groomed Salman Abedi into a radicalised Islamist extremist, the inquiry heard.
The chairman of the inquiry Sir John Saunders ordered Mr Taghdi to attend on Thursday but he has so far refused, even though he has the legal right to refuse to answer any questions that could incriminate himself.
