The German government on Wednesday denied reports that one of its nationals had been arrested in Lebanon on suspicion of spying for Israel, DPA reported.
A spokesman for the foreign ministry in Berlin said that there had been "no proceedings" instigated against Manfred Peter Mog, 58, an engineer who had worked for a dairy company in eastern Lebanon.
According to reports Tuesday, Lebanese army intelligence arrested the man on charges of spying for Israel.
The Berlin spokesman said that Mog had been questioned by Lebanese authorities, but was had not been arrested or otherwise detained.
Mog, who worked at the dairy factory Liban Lait, near the ancient city of Baalbeck, had been in charge of the maintenance of all equipment in the facility.
Lebanese security sources said Tuesday that Mog had been questioned about sophisticated transmitters in his possession.
The foreign ministry in Berlin gave no further details of his questioning.
The factory where Mog worked was destroyed during the July 2006 Israeli conflict with Lebanon.
In the past year around 70 people have been arrested in Lebanon on charges of spying for Israel.
Last week the Lebanese cabinet unanimously agreed to file a complaint with the UN Security Council against Israel, over alleged spy rings uncovered in Lebanon.
Israel has not commented on any of the Lebanese charges.
The 13-member Hezbollah bloc in the Lebanese parliament stressed "the need to uncover and execute individuals charged with collaborating with Israel."
Under Lebanese law, convicted spies face life in prison with hard labour or the death penalty if found guilty.
