A man has been arrested following a police operation at a Sydney property linked to outlaw motorcycle gang the Gypsy Jokers.
The operation came after the alleged assault of a woman at Penrith earlier in the day, police said.
Officers from Nepean police command were called to a home in Colless Street, Penrith about 2.10pm on Tuesday following reports that a woman had been assaulted.
Officers were told a man then fled to a property on The Horsley Drive in Horsley Park.
Specialist police, including the public order and riot squad, police rescue, officers from Fairfield and the traffic and highway patrol command set up a perimeter at the clubhouse about 2.30pm.
Police confirmed in a statement that a 29-year-old man was arrested without incident at about 4.40pm.
He was later charged with kidnapping, assault and intimidation, a NSW Police spokesman said.
The woman was taken to Nepean Hospital in a stable condition.
A crime scene has been established at the bikie clubhouse, with police saying investigations are continuing.
Vision from the scene showed the man walking towards police with his hands up, briefly lifting up the hem of his shirt, before a large green gate at the front of the property slid open.
Riot squad officers then held the man on the ground, handcuffed him, and led him away.
The “fortified” clubhouse is at the centre of a NSW Supreme Court case where police are attempting to have it declared a restricted premises.
Police allege the property is home to “indecent conduct and entertainment of a demoralising character”, is used to unlawfully sell or supply alcohol, and has been attended by “reputed criminals” who are likely to attend again.
Last month, the court heard police launched a 2014 raid on the property after they received information “that the Gypsy Jokers had stolen an alpaca and were having sexual intercourse with it” at the location.
A barrister acting for the club said there was “simply no evidence” such an act took place.
In documents tendered to the court, the clubhouse was described as having a stage, a bar, a pool table, a “stripper pole” which was later removed, an office and a members only area.
Police described the property as a “large compound” with a “fortified front entrance”, an electric gate, concrete blocks and an “extensive CCTV system”.
Inside the compound were multiple buildings, including the main clubhouse, a workshop, caravans and other accommodation.
