Banksy reindeer mural covered after red noses added

A mural by Banksy has been covered with a perspex sheet after the artwork appears to have been vandalised. The mural depicts two reindeer pulling a bench as if it were a sleigh, but now the reindeers sport two bright, red noses. The painting, which aims to highlight the issue of homelessness in Britain, appeared on the wall in Birmingham over the weekend.
