Police have carried out further searches on Saturday around the Comber area of County Down for a missing man who is believed to have been murdered.

Pat McCormick, a 55-year-old father of four, was last seen in Comber on Thursday 30 May.

Saturday's search was land focused, with police investigating "main routes in and out of Comber".

A previous search saw police divers enter a lake in the wetlands beside Strangford Lough.

Police have said thousands of hours of CCTV footage have been gathered as part of the investigation.

They have also spoken to about 100 people.

On Saturday, DUP councillor William Walker told BBC News NI that Mr McCormick was "well known in the area".

He added: "I just hope Pat's body can be recovered and returned to his family."

A man and woman in their 20s were arrested last week on suspicion of Mr McCormick's murder, but were later released on bail pending further enquiries.

Two other men arrested as part of the investigation were also released on bail.
