Security officials in German on Monday released Al-Jazeera reporter, Ahmed Mansour, without leveling any charge against him.

Mansour was briefly detained on Saturday by the German police at Berlin’s Tegel airport after Egypt issued an arrest warrant against him.

Egypt’s military regime specifically requested for the journalist’s arrest, it was learnt.

A spokesman for the state prosecutor in Egypt said there were political and diplomatic concerns that could not be ignored in addition to the legal aspects of the case.

These concerns, he noted, were discussed with the Berlin state justice minister and the appropriate federal authorities.

A lawyer assigned to Mansour, who incidentally has a dual Egyptian and British citizenship, said that while his client was happy about his release, he was nevertheless concerned about his illegal detention by the Germans.

A German government spokesman said on Monday that the authorities acted on an Interpol “red notice” system alarm.

The Interpol however denied the existence of such red notice against Mansour’s name.

Political pundits believe that the controversy may have been based on political expediency.

There are unanswered questions why the reporter was arrested and detained for possible extradition despite the fact that Germany is not under any legal obligation to extradite detained persons to Egypt.

Also, legal experts opine that the warrant of arrest could not have been executed by German security operatives without clearance from the government.

The outcry of legislators against Mansour’s illegal detention across Germany may have led to his eventual release.

Reporters Without Borders on Monday advised Germany “not to become an accomplice to the Egyptian regime.”

The German Journalists Association also noted that based on Egypt’s use of the death penalty, Mansour should not be sent back to the country.

It would be recalled that in 2014, an Egyptian court convicted Mansour in absentia on claims that he tortured a lawyer in Tahrir Square in 2011.

Mansour was sentenced to 15 years in prison but he rejected the charges, calling them an attempt to tarnish his image.

Egypt currently accuses Qatar and the Al-Jazeera of supporting the Muslim Brotherhood, which has been branded a terrorist organization by Cairo.

Three journalists working with Al-Jazeera English spent more than 400 days in prison after they were arrested in Cairo in 2013.
