Police on Sunday were questioning a 23-year-old Pakistani national in connection with a double homicide on Saturday night on the island of Evia.

The suspect was arrested by officers during a large-scale investigation into the murder of a married couple in Aliveri, southeast of Halkida, on Saturday night. The 54-year-old woman and her 56-year-old husband were found dead by police officers responding to a call from their daughter in Athens, who said that she had been trying to get in touch with them for several hours but was unable to.

Officers of the Halkida precinct sent to investigate the daughter's concerns found the mother dead in the back yard of the home and the father's body in the bedroom. Both showed signs of violence, though a coroner's report on the exact causes of their deaths is pending.

The 23-year-old suspect was being questioned along with another six men who are facing charges of harboring a criminal.
