Three men employed as teachers or teaching staff in Birmingham have been arrested in the UK for alleged possession of extreme pornography.

Two of them (aged 36 and 37) were detained at their homes in the city; while the third (32) was held at his property in Wolverhampton just after 6am.

They are being questioned by detectives from the public protection unit of the West Midlands force at police stations in the region.

One of the men works at Park View School and the other two are employed at Golden Hillock School. Police have notified the suspects' employers as well as the British Department for Education.

The force said its investigation began in April 2013 as a result of an on-going enquiry into the sharing of extreme pornography.
