A man arrested at a Birmingham station under anti-terrorism laws will not face any charges, a West Midlands Police spokesman has said.
The arrest was made at the metro station close to the train station
The man was arrested at Snow Hill metro station in the city centre on Friday.
He was reportedly carrying two suitcases which were checked by explosives officers.
The station was evacuated shortly after 1800 BST and reopened two hours later. A spokesman later said the incident was not suspicious.
Insp Phil Milton, from British Transport Police, told reporters later that the packages were not found to be suspicious.
"The bomb disposal team have been and checked and found it to be safe," he said.
He revealed that the alarm was raised by an off-duty officer who saw a man and believed his behaviour to be suspect.
The man, said only to be an adult who had travelled from London, was on the tram at the time.
Asked if the arrest was connected to the London bombings, the officer added; "as far as I know its wholly unconnected."
The arrested man has been interviewed by officers but will not charged with any offences.
Part of Snow Hill station is below ground level.
