Green Lane Masjid

Green Lane Masjid, a Birmingham mosque that Channel 4's Dispatches documentary Undercover Mosques investigated for extremist preaching. Through 2015 the opening said the mosque "featured in Channel 4's Dispatches programme Undercover Mosques, which documented Islamist extremism in British mosques including preachers advocating violence, anti-semitism, sexism and homophobia." Today the word appears 0 times in the opening, though it survives once in the body. A reader today does not learn that an investigative documentary recorded preachers at this mosque advocating antisemitism.

The opening as it read in 2010

Green Lane Masjid , commonly referred to as 'Green Lane Mosque', was established in the 1970s, is one of Birmingham's and Britain 's major mosques, and the national headquarters of People of hadith .1 The Masjid occupies a prominent corner site in Green Lane, Small Heath , Birmingham, with one of the buildings having been constructed as a public library and baths , designed by local architects Martin & Chamberlain and built in the redbrick and terracotta Gothic-Jacobean style, between 1893 and 1902. It is a Grade II listed building .2 The complex includes prayer halls for men and women, a community hall, madrasah, library, shop, some accommodation, and provides funeral services to the local Muslim community.3 It was also one of the main mosques that featured in Channel 4's Dispatches programme Undercover Mosques, which documented Islamist extremism in British mosques including preachers advocating violence, anti-semitism , sexism and homophobia.4 West Midlands Police subsequently investigated the programme, feeling there may have been a mis-representation of the mosque, that could have incited religious hatred, though Ofcom later reported that the programme had "accurately represented the material it had gathered and dealt with the subject matter responsibly and in context".5
