German police have confirmed a detonation outside a migration facilitation centre in Zirndorf, a town near Nuremberg.
Local media reports said a suitcase most likely to be filled with aerosol spray cans exploded near the reception area of a refugee registration centre in the Bavarian town. The incident happened at 2.30 pm local time.
Police denied that there was an explosion.
“There is no indication at the moment that a bomb was detonated in the suitcase,”a statement from the police said.
“It is possible it was a spray can inside the suitcase that caused the explosion. No one was reported injured,” police said.
Eye witnesses claimed that people fled the scene soon after a loud bang was heard.
Police are looking for a man and a woman who are suspected of leaving the suitcase behind.
Germany has been on the edge following a series of violent events in the past ten days. Most of these attacks have been in the southern state of Bavaria. A refugee, earlier believed to be from Afghanistan had axed five commuters on a passenger train near Wurzburg. The teenager was shot dead by the police as he tried to flee after the attacks.
Another gunman went on a shooting spree on Friday in Munich killing nine people.
On Sunday, a Syrian refugee who was denied asylum had blew himself up at the entrance of a music festival at Ansbach, a town some 30 minutes drive from Nuremberg.
