Police say a man arrested after a home-made explosive was found near a mosque in Walsall has been bailed pending further enquiries.
The 75-year-old was arrested on Thursday on suspicion of causing an explosion likely to endanger life or damage property.
Witnesses say the device exploded outside the mosque on Rutter Street last Friday night (21 June).
Despite a 'loud bang', nobody reported the explosion.
The next day debris was brought inside the mosque and police were alerted.
A major investigation involving specialist detectives and experts from the West Midlands Police Counter Terrorism Unit is continuing.
