**Police are still hunting for a man who fled after his computer sparked a security alert at a German airport.**Part of Munich airport was closed for hours on Wednesday as the traveller’s laptop set off an explosives detector.
Some 1,000 police spent the evening scouring the airport for the man who hastily left the security area with his laptop as the alarm was raised.
He may not have realised he was meant to undergo a further check, a police spokesman said.
Airports around the world have been on heightened alert since an alleged attempt to blow up a US airliner flying from Amsterdam to Detroit last month.
On Thursday, US Homeland Security Secretary Janet Napolitano is in Spain to discuss European airport security with EU ministers.
Security questioned
Wednesday’s security breach was unacceptable, Germany’s police union said, calling for a thorough investigation into security at German airports.
“If you’re checking someone, you have to be able to hold onto him,” Josef Scheuring, the union’s chairman, told Sueddeutsche Zeitung newspaper.
Some 60 flights were delayed or cancelled as a result of the alert, which closed Germany’s second busiest airport for three hours from 1530 (1430 GMT).
Initial reports said explosive traces had been found during the check. But federal police spokesman Albert Poerschke said later the activation of the alarm did not “have to mean that there were explosives inside” - the scanner may have been set off by chemicals such as perfumes.
Officials had wanted to check the computer again but the man had left, police said.
It was possible he may not have realised further inspections were required, and had simply been in a hurry to catch a flight, they added.
Munich airport is situated about 30km (20 miles) north-east of the city in southern Germany.
