A 25-year-old man being questioned over explosions at three mosques in Walsall, Tipton and Wolverhampton has been arrested in relation to what police are calling "a further act of terrorism".
He is being held in connection with the murder of 82-year-old Mohammed Saleem Chaudhry, who was stabbed three times in the back as he walked home from a mosque in Small Heath, Birmingham in April.
