No further details were provided on her suspected role in the escape plan.
Acting Principal Magistrate Peony Wong Nga-yan granted the woman bail after prosecutors raised no objections to her temporary release.
The defendant was told to observe a travel ban, surrender all relevant documents, report to police twice a week and notify the force about any change of address.

Abby Choi murder: seventh suspect arrested in mainland China, recovery of body parts continues
The high-profile case came to light on February 24, when officers found body parts belonging to Choi, 28, who had been reported missing, in the ground-floor flat of a three-storey house in Tai Po’s Lung Mei Tsuen.
Police found two pots containing a skull and several ribs, alongside meat cleavers, a hammer, face shields, black raincoats and a purple handbag that belonged to Choi at the flat. Two legs were also found in a refrigerator.
DNA tests later confirmed the skull and legs were Choi’s. Her torso and hands are still missing.
Kwong, 28, alongside his 65-year-old father Kwong Kau, and brother Anthony Kwong Kong-kit, 31, were earlier charged in connection with Choi’s murder and remanded in custody without bail.
His mother, 63-year-old Jenny Li Sui-heung, was also denied bail after being charged with perverting the course of justice.
A 41-year-old yacht rental agent accused of helping Choi’s ex-husband escape to Macau by sea was released on a HK$50,000 bail on a charge of assisting an offender.
Another 47-year-old woman accused of helping Kwong evade police has not been charged yet.
