Former Auburn deputy mayor Salim Mehajer has been slapped with drug dealing charges a week after being declared bankrupt.

In the latest blow for Mehajer, who has been behind bars charged with conspiracy to pervert the course of justice and conspiring to cheat or defraud since January, he has now been charged relating to the possession of anti-anxiety and heavy-duty painkillers, The Daily Telegraph reports .

The charges will be formerly laid on Wednesday when Mehajer attends court over a car crash last year, which police claim was staged in order to dodge a court appearance

A number of Alprazolam, Targin and Endone tablets were discovered by police during a raid on Mehajer's Lidcombe home on November 8, as they searched for evidence in relation to the car crash.

Last week a Federal Circuit Court judge declared the 31-year-old former property developer bankrupt .

It comes in the wake of a successful suit against Mehajer over his failure to pay $596,176 for a marble staircase purchased for his Lidcombe home.

Mehajer is fighting legal battles in relation to claims of electoral fraud and breaching an AVO taken out by former wife Aysha Learmonth.

He also stands accused of defrauding an insurance company and is currently on a good behaviour bond over the assault of a taxi driver in April 2 last year.

Mehajer did not attend court last week and has been refused bail three times.
