The attacks happened less than a week after a white supremacist allegedly shot 50 Muslim worshippers dead in Christchurch, New Zealand.
And they have left Muslims in Birmingham in fear.
CCTV footage from Witton Islamic Centre shows a man in a hoodie smashing the window with an object - believed to be a sledgehamer - before sending shattered glasses into the mosque.
He then quickly sprinted away from the scene.
The five targeted mosques are the Witton Islamic Centre, the Masjid Faizul Islam, the Jam-E-Masjid, Muslim Community Centre Aston and Al-Habib Masjid – all within two miles of each other.
West Midlands Police say they are treating all five attacks as linked and counter-terror police are working with them on the investigation.
