SALIM Mehajer is expected to face court later today after allegedly breaching an apprehended violence order.
The controversial former deputy mayor of Auburn was arrested overnight following a car crash at Kingsgrove and for allegedly breaching the AVO that prevents him from seeing his estranged wife Aysha Learmonth.
The 31-year-old is in custody at Campsie Police Station after an accident in Kingsgrove in Sydney's south.
It is expected he will be refused bail until he appears in Burwood Local Court later on Monday.
Mehajer told a court last week he and his wife were still happily married.
"She wants to get out of the media and acts like she's not with me but she is with me," he said. "We are still talking."
The lavish wedding in 2015 catapulted the couple to national stardom.
The extravagant outdoor ceremony, which saw Aysha and Salim tie the knot, involved four helicopters, a jet, a sea plane and a motorcade of luxury sports cars and motorcycles.
But within 12 months the fairytale romance looked to have turned into a nightmare.
The arrest comes after a tough weekend for the Mehajer family.
Mehajer's sister Aisha on Saturday married Hassan Sam Sayour, the nephew of notorious Sydney nightclub identity John Ibrahim.
But on the eve of the wedding, John Ibrahim's bodyguard Semi "Tongan Sam" Ngata was shot in the back in what was rumoured to be a bid to stop the nuptials.
The wedding was mere metres away from the scene of the shooting, an act police described as a "brazen and targeted" attack.
