WARSAW, Ramadan 08, 1436, June 25, 2015, SPA -- Polish police acting on a tip-off from a hoax caller searched a Ryanair jet for an explosive device on Thursday but found nothing, police and the airline said, according to Reuters. A spokesman for Warsaw police said a 48-year-old man had been detained after the hoax call was traced to his home. "This was an irresponsible prank," the spokesman, Mariusz Mrozek, told Polish broadcaster TVN24. Ryanair said the jet was on the tarmac at Warsaw's Modlin airport, waiting to board for a flight to Oslo, when the call came in. The airport was temporarily closed to incoming and outbound flights as a precaution. Police bomb disposal officers were called in to conduct checks on the aircraft, and found no explosives on board, said Edyta Adamus, a spokeswoman for Warsaw police. --SPA 13:58 LOCAL TIME 10:58 GMT www.spa.gov.sa/w
