01147001404 HMRC Scam Telephone Calls

I received a scam call from 01147001404 where the caller claims she is from HMRC and there is a fraud case against. The caller then claims if I don't press "1" the police will be around to arrest me. Then I got another call, claiming I own Taxes and HMRC would issue a warrant for my arrest if I didn't press "1". These scam calls are getting ridiculous.
