Four quizzed over porter's death

Four people were tonight being questioned about the killing of a hospital porter at his flat near Belfast.

David Hamilton, 40, was found dead in the property on the Ballybeen Estate in Dundonald last Monday.

Mr Hamilton, who lived alone and worked at the nearby Ulster Hospital, is believed to have suffered serious head injuries.

Detectives are trying to work out if he was murdered when a burglary turned violent.

Two men were brought in for questioning within 48 hours of the killing and police tonight confirmed another four people had been arrested.

They were being held while investigating officers decided whether to press charges.
