Man charged after violent NSW robbery

A man has been arrested at Sydney Airport and charged with a brutal robbery in northern NSW last year.

A 37-year-old man was allegedly tied up and assaulted with a gun and stun gun in his Wooli home, near Grafton, on October 13.

Four men allegedly broke into his house and stole cash, jewellery and a vehicle before escaping.

Police arrested a 26-year-old man at the airport after he arrived on a flight from Canada about 10am on Saturday.

He was charged at Mascot Police Station with robbery in company while armed with a dangerous weapon.

The man is due to face Parramatta Local Court on Sunday.

The charge follows the arrest of a man in December, who was allegedly part of the robbery.

A 41-year-old Bonville man is before the courts, charged with robbery with a dangerous weapon, possessing suspected stolen property, and having custody of a knife in a public place.

Police investigations continue.
