Airport police at Milan"s Malpensa hub said Tuesday no traces of explosive were found in a suspect parcel discovered in a toilet situated near row of check-in counters. Bomb disposal experts used a high pressure hose to spray water on the parcel which had appeared to contain a remote detonation device, including wires and possibly a small antenna. Authorities suspect the parcel may have been planted to cause alarm. Police cordoned off the area where the parcel was found, but no flights at the airport, one of Europe"s largest hubs, were disrupted, the SEA airport company which controls Malpensa said.
