Salim Mehajer allegedly caught up in NRMA fraud

NSW police are investigating several fraudulent insurance claims allegedly linked to former Auburn deputy mayor Salim Mehajer.

There have been a series of similar collisions allegedly involving cars registered to Mehajer and his companies, all of which have been claimed through NRMA, Seven Network reported.

"The NSW Police force has recently received referrals relating to reported fraudulent comprehensive vehicle insurance claims...Investigations are underway," police told AAP on Wednesday.

Two collisions last year were strikingly similar to Mehajer's most recent crash on Monday, where he was stretchered into an ambulance wearing a neck brace, stopping him from fronting court on assault charges.

An insurance assessment review found the cars were likely stationary when struck, Seven Network reported.

A NRMA Insurance spokeswoman said insurance fraud is taken "very seriously", and measures are in place to prevent, detect and respond to fraud.

"Fraud and claim exaggeration have recently been at historically high levels and we're pleased to see that the NSW police taskforce has already resulted in many insurance fraud arrests and prosecutions," the spokeswoman told AAP.

"We are not able to disclose personal information regarding our customers or any investigation activity."
