A man in his 20s who was arrested on suspicion of trying to carry explosives onto a plane in Sweden has been released without charge.

The suspect, a German national, was detained at Landvetter airport, in Gothenburg, on Thursday morning after authorities found what they believed was explosive TATP in his luggage.

However, he was released without charge on Friday as authorities admitted the 'bomb' was likely nothing more than food.

Local media reported the man had been carrying containers filled with TATP, an explosive commonly used in terror attacks. Police tested the substances, before saying there was 'no evidence of a crime' (pictured, the man's luggage)

When asked what police had discovered in the man's bag, chief Erik Nord told public broadcaster SVT: 'That's for the lead investigator to answer, but it looked like food.'

A statement from investigators had earlier said: 'An analysis of the suspicious objects has been made during the day and the man is no longer suspected of any crimes.

'The prosecutor is not able to comment further on the decision.'

Police had discovered two cans containing a brown liquid and another containing a white liquid in the man's luggage, according to local newspaper Göteborgs-posten.

An image published by national newspaper Aftonbladet showed the man being escorted from the airport by officers.

He was arrested and charged with 'attempted general devastation'.

Officers said the man was stopped after a routine check found evidence of suspicious items. They would not say what was actually found inside the containers

Landvetter airport was temporarily placed on lockdown while bomb squads were called in, but the cordon was lifted a short time after

Part of Landvetter airport was closed down by bomb squads while the determined if the containers were safe to move.

Later in the day the objects were taken away for testing and the airport reopened.

The man was attempting to fly to another EU country but was arrested going through the security check for domestic flights, The Local reports.

TATP, short for triacetone triperoxide, is difficult to detect and as such is commonly used in terrorist attacks, particularly those linked with ISIS.

It was used to make the suicide vests used during the 2015 Paris attack, and again in the rucksack bomb that killed 22 during the Manchester Arena bombing.
