Detectives attached to Strike Force Bukari yesterday arrested and charged a 17-year-old girl and 41-year-old man over the alleged conspiracy.

They are charged with conspiring to murder a 26-year-old Bathurst man police claim was kidnapped, starved and beaten while being held captive for six months at a home in Fish Parade, Gorman’s Hill earlier this year.

The 17-year-old girl was arrested in Blacktown, in Sydney’s west, about 9am yesterday before detectives arrested Mervyn John Ferry in Bathurst about 11am.

Ferry was already in police custody after being refused bail over the kidnapping charges in August. He appeared in Bathurst Local Court yesterday afternoon during a hearing that lasted just five minutes.

Chifley local area command Detective Sergeant Andrew McLean told the court “it is the same victim”, referring to the 26-year-old man police allege had been kidnapped by Ferry and a co-accused, 46-year-old Paula Diane Morrison.

Ferry, a greying man wearing a green t-shirt and shorts and white running shoes, sat handcuffed in the dock as Sgt McLean handed Local Court registrar Mark Nicholls a charge sheet indicating that Ferry conspired to murder the 26-year-old between 12.01am on Wednesday, September 3 and Wednesday this week at Bathurst.

Solicitor Simone Murdoch told Mr Nicholls there was no need for the police to tender a statement of facts about the latest charge against Ferry.

He had been bail refused in custody and would return to the court on Monday, November 29, Ms Murdoch said.

Sgt McLean said police did not object to the adjournment.

While Sgt McLean was not required to tender the facts sheets yesterday in Bathurst, police media said the arrest of the girl and Ferry followed an investigation into an alleged plot to kill the victim of a kidnapping who had been expected to give evidence against Ferry.

Ferry and Morrison were arrested after they allegedly kidnapped and held the 26-year-old Bathurst man captive in a house in Fish Parade, Gormans Hill for about six months.

Police alleged Ferry and Morrison held the man against his will at Gormans Hill where he was forced to perform domestic duties in the home where he paid $80 a fortnight board and $50 for food.

It has been further alleged the man had been starved of food and weighed just 40kg when taken to Bathurst police station by Ferry, who sought to make a complaint against the 26-year-old.

Police said they found the man extremely dehydrated and in an emaciated state.

The man had been treated at hospital in Bathurst and Sydney, where a number of old and new injuries had allegedly been revealed.

It will be alleged the man suffered repeated beatings with an iron bar, fists and feet.
