Authorities in Spain were forced to evacuate train stations in Barcelona and Madrid over a suspected explosive device that turned out to be a belt buckle shaped like a grenade, local media reported.
Two trains in Barcelona's central Sants station were evacuated at around 8am on Wednesday, in order to allow police to search for an object shaped like a possible explosive device detected inside a suitcase.
The alarm was sounded by a security scanner in Sants, before Tedax, Spain's bomb disposal team, realised the case was travelling to the capital.
Shortly after Sants reopened, Madrid's Atocha station - the site of a bombing that killed 193 people 14 years ago - was shutdown on an order by police.
According to Cadena Ser, the bomb scares were triggered by a grenade-shaped belt buckle stored in the suitcase of a woman who was travelling from Barcelona to Madrid.
After tests by a bomb disposal team, Catalan police said the suitcase represented no danger.
Atocha, however, was evacuated around 10am, with commuters saying they were forced to "run out into the street", before authorities confirmed the false alarm and reopened the station less than an hour later.
The station was the site of Spain's deadliest militant attack in March 2004. More than 2,000 people were injured on top of the 193 killed. Police say it was carried out by Islamist militants inspired by Al-Qaeda.
Police closed two train lines in Barcelona's main station on Wednesday after a security scanner detected an object inside a suitcase that could be an explosive, TASS reports.
Bomb disposal teams had been sent to the Barcelona Sants station.
“We have received notification about 8 am (0700 GMT). Security of (rail company) Adif has seen an object with a scanner the shape of a possible explosive device inside a suitcase. We continue to make checks,” Catalan police said on Twitter.
