Two men have been arrested after five mosques had their windows smashed in Birmingham on Thursday, West Midlands Police said.
A 34-year-old man from Perry Barr handed himself into a Birmingham police station and was arrested on suspicion of racially aggravated criminal damage.
A 38-year-old man from Yardley was also arrested on suspicion of racially aggravated criminal damage on Friday afternoon after being detained by members of the community. Both remain in custody on Friday evening.
Assistant Chief Constable Matt Ward said: “This is a significant step forward in our enquiries however the investigation continues into the motive for the incidents.
“We are working extremely closely with mosques and local communities around the West Midlands and this will continue.
“It remains incredibly important that we unite together against those who seek to create discord, uncertainty and fear.”
Five Birmingham mosques had their windows smashed in the early hours of Thursday between 1.25am and 3.15am.
The mosques are Witton Islamic Centre, Aston, Masjid Madrassa Faizal Islam, Perry Barr, Al Habib Trust, Aston, Jamia Mosque, Aston and Ghousia Mosque, Erdington.
The police said increased patrols would continue at key locations to reassure communities and security advice is being provided to religious establishments across the West Midlands.
The investigation is continuing and the police are being supported by West Midlands Counter Terrorism Unit.
