Police stepped up security at airports in southwestern Germany this week after two men were spotted apparently observing security checks in Stuttgart and authorities received a tip about online talk of attack plans. A similar sighting was reported at Paris' Charles de Gaulle airport.
Police said Friday they tracked down the men seen in Stuttgart, who turned out to have been watching a woman they had taken to the airport go through security. Checks on a German man whose car was seen at the Paris airport also produced no evidence of attack plans.
Security was returned to normal levels.
