FOR more than a decade, Sam Prassad was entrusted with the welfare of a largely non-English speaking Indian workforce at Rorato Nominees' tomato farm in Jerilderie, in southern NSW.

During that time, he faced four separate complaints of alleged sexual or indecent assault.

Last week, NSW Police confirmed it had forwarded a "brief of evidence" to the Department of Public Prosecutions (DPP) over a fifth incident - the alleged 2007 sexual assault of female Indian factory worker Rashmika Patel.

The employment agency - Primary Contracting Services - that paid Mr Prassad to manage migrant contract workers, has now sacked him.

PCS manager Anthony Boots said: "My No.1 priority is a safe work environment for my contractors. If I think it may not be safe, I have a duty of care to do something about it. He'll never contract with our agency again."

In January, a Sun-Herald investigation uncovered human rights abuses involving hundreds of Indian nationals in Jerilderie. They arrived in Australia on holiday visas, then secured bridging visas. While their asylum appeals were being processed, the tourists were directed to Rorato.

Local lawyer Dale Brooks is overloaded with legal cases relating to Mr Prassad and migrant abuse. "Once they arrive, they are at the mercy of Sam Prassad," he had told the Sun-Herald previously.

Former workers claimed they were forced to hand Mr Prassad job-enrolment fees of up to $4000 a couple, and that as a condition of employment, they had to pay to live in two ramshackle, one-bed "communes" owned by Mr Prassad, who denies the claims.

In May last year, Mrs Patel complained to Deniliquin police that Mr Prassad sexually assaulted her twice but the investigation stalled. Police Minister David Campbell later ordered an internal investigation over "the length of time taken to reach this point".

The NSW Ombudsman is acting on a complaint from Mrs Patel's lawyer about the delay.

The Greater Southern Area Health Service also complained that police left Mrs Patel without support services of any kind.

When The Sun-Herald confronted Mr Prassad, in January, about Mrs Patel's assault allegation, he said: "It's bullshit and lies.

"I've never been involved with anything like this before."

It emerged, however, that in 2004, another Indian worker told police that Mr Prassad sexually assaulted her. In 2002, three local women launched separate legal proceedings against him, alleging sexual harassment.

Rorato Nominees and Mr Prassad settled out of court without admitting liability, paying each woman $8000 in "general damages".

A Rorato family spokesman said he hoped Mr Prassad's departure would bring an end to the "bad publicity". Rorato's lawyers previously said Prassad had been counselled and asked to avoid contact with staff which could lead to harassment claims.

The DPP has completed a review of police evidence relating to Mrs Patel's case, but Mr Brooks fears prosecution is unlikely.

Mr Prassad is in Fiji and could not be reached for comment.

The Minister for Immigration and Citizenship, Senator Chris Evans, will introduce new laws in September to "help prevent the exploitation of temporary skilled foreign workers".
