E-mails from Lancashire Police requesting more information

Received an e-mail from Lancashire Police a few days ago. They are still up to their old tricks. Refusing to take a statement but keep on asking for more and more information in the hope it wear me out and I will give up. What does it take to get the Police to take a statement? Why do the Police and Civil Service think Her Majesty's Revenue and Customs are above the law? Racial harassment is wrong and should never be tolerated - but clearly that's not the view of others. Have sent documents to the police. Penny to a pound they will ask for something else and still refuse to take a statement.
