One of the conspirators who allegedly helped Salim Mehajer stage a car crash to avoid court last year was captured by a surveillance device saying Mehajer's lawyer told him to stage the smash, according to court documents.

Ahmed Jaghbir, 28, was arrested in January and charged with perverting the course of justice and conspiracy to cheat and defraud after he allegedly organised a woman to crash into Mehajer's car at a Lidcombe intersection on October 16, 2017.

Mehajer, who had been driving to a court hearing in Sydney's CBD to face charges of assaulting a taxi driver, had to be cut out of his car and taken to hospital.

Seven people including Mehajer have since been charged over the crash, with police alleging Mehajer's car had been insured at an inflated price nine days earlier and the crash served the dual purpose of avoiding court and defrauding an insurance company.
