Temperatures remained well below the freezing point in many parts of Greece yesterday, and conditions are expected to deteriorate today. Search teams seeking a father and son carried away by a torrent in spate in Patras five days ago yesterday discovered the drowned body of Alexios Antonopoulos, 53, off the beach of Lakopetra, 20 kilometers west of the northwestern Peloponnesian town. There was no trace of his nine-year-old son, Yiannis. The two were lost when the Diakonaris torrent broke its banks on Sunday. On Mt Olympus, rescuers found Thessaloniki businessman Efstathios Iosifidis, 47, who had been missing since Sunday in the Prionia area. He was in good health. Yesterday, Transport Minister Christos Verelis apologized to the 118 train passengers who were trapped for 15 hours on Monday and Tuesday in unheated carriages in Thrace. The railwaycompany promised each passenger 100,000 drs in compensation. Adding to the confusion, the mayors of Perama and Keratsini closed down the Schistos rubbish collection dump yesterday, demanding that Attica’s local authorities pay them 400 million drs in compensation for the use of the location this year.
