A solicitor and two allied health professionals were last week charged over alleged roles in a group co-ordinating fraudulent compulsory third party (CTP) insurance claims in Sydney.

The arrests were part of a crackdown by the NSW Strike Force Ravens team, formed following recommendations by the CTP taskforce.

Detectives arrested the 43-year-old solicitor at an office in Auburn and charged him with 11 counts of fraud and directing a criminal group.

A 31-year-old man from Croydon Park was charged with 11 counts of fraud, two counts of making false documents, using a false document and directing a criminal group.

The third man, aged 30, was arrested at Bankstown and charged with 11 counts of fraud, 16 counts of publishing misleading material to obtain financial advantage and directing a criminal group.

Strike Force Ravens investigators have now arrested 16 people and laid more than 120 charges in relation to a combined fraud of more than $11 million. Further arrests are expected.
