More than 80 officers from HMRC searched three private and 12 business addresses in Bath, Bournemouth, Bristol, Berkshire, Exeter, Stroud, Swindon and Yate last Wednesday, October 4.
Seven men and three women were arrested and interviewed by HMRC. Computers and business records were seized during the operation. Those arrested were released pending further investigations.
Colin Spinks, assistant director of fraud investigation at HMRC, said: “Tax fraud is often thought victimless but it isn’t; the public lose out on vital funds for essential services. We will continue to work with our partners to tackle this crime.”
