Salim Mehajer put a tracking device on his wife's car and "bombarded" her with up to 70 calls a day before having an AVO issued against him, The Daily Telegraph reports.

It was alleged in the Wollongong Local Court yesterday that Mr Mehajer installed the device on his wife’s car after a series of erratic displays of behaviour.

Yesterday’s proceedings were held to finalise the interim AVO placed against the former Auburn deputy mayor and address his controlling behaviour towards Ms Learmonth, the newspaper reports.

According to details contained in court papers, Mr Mehajer allegedly engaged in erratic behaviour following his wife's decision to leave their family home.

Such behaviour included “bombarding” her with emails and phone calls, with claims he once phoned her 70 times in one day.

Another instance involved the businessman filling a missing person's report because Ms Learmonth was five-hours late to meet him and he feared she had been abducted.

As a result, he told police he installed a tracking device on her car and showed them maps as proof.

Mr Mehajer previously wrote on social media that "only death" would separate him from his wife.

Mr Mehajer’s AVO prevents him from physically “assaulting, molesting, harassing, threatening or stalking” Ms Learmonth for nine months.

However, it has been amended to remove a clause preventing him from contacting or approaching her.
