Mother of the Hells Angels bikie Peter Zervas has taken back $20,000 in cash she had provided to keep her son out of jail after he was charged last week with threatening her and damaging property at the family's unit in Lakemba.Yesterday Fredericka Bromwich asked Central Local Court to recover the money she had provided to ensure her son's freedom as he faces charges of riot and affray in relation to a brawl between members of two rival bikie gangs at the domestic terminal of Sydney Airport in March.Her youngest son, Anthony, was killed in the melee after he was allegedly hit in the head with a steel post. Eleven Commanchero have been charged with his murder.Police allege that Mr Zervas, who was shot five times as he returned home days after the brawl, destroyed or damaged hundreds of dollars of his mother's property, including six ceramic plates and a glass dinner table, nine days ago.The next day police charged him with stalking, intimidating and intending to cause his mother physical or emotional harm. He was also charged with possessing ecstasy and 46 tablets of the anti-anxiety drug Xanax.Mr Zervas faced Burwood Local Court last week charged with the offences and was granted bail. But on Wednesday he was arrested and taken into custody by police after his mother indicated that she wanted to withdraw her financial support.The court had previously required that Mr Zervas live at the Lakemba unit, but that condition was deleted.

Yesterday the magistrate Jane Culver added a further condition to his bail: that he not contact or approach his mother or go within 100 metres of her property.A family friend later provided security and Mr Zervas walked free from the court yesterday afternoon. The case will resume on March 18.
