Five charged after violent home invasion

A group accused of a violent home invasion and kidnapping are set to face court in mid-December.

The four men and one woman were charged this week over their alleged involvement in the kidnapping of a 21-year-old man at a house in Hornsby, in Sydney's north, in late August.

Detectives on Wednesday arrested three men aged 19, 27 and 32, and charged them with assault and kidnapping offences.

The 19-year-old was also charged with possessing a prohibited drug.

All three were refused bail to appear at Central Local Court on December 18.

A 21-year-old Pennant Hills man was also arrested and charged with kidnapping and was granted conditional bail to reappear December 18.

A 51-year-old Asquith woman was also charged with hindering a police investigation.

She was granted conditional bail to appear at North Sydney Local Court on November 26.
