Now the Guardian is reporting this:
Police are hunting an elderly letter writer responsible for sending more than 50 racially abusive letters to people across the country, including the prime minister.
The letters, some sexually explicit in content, have been sent to schools, hospitals, mosques, universities, doctors' surgeries and private individuals, leaving some recipients "extremely distressed".
According to Hampshire police, which is heading the investigation, the letters are all pro-English in content and racially inflammatory, with many appearing to have been sent in response to Daily Mail articles. All the letters are offensive and racist against a wide variety of nationalities and cultures...Clippings from the Daily Mail have been included in many envelopes.
Some of the letters are just about readable on the Times website.
