The stadium can hold more than 75 thousand fans and the suspect package was found when they were filing in. Players immediately left the field, and an evacuation began. A full search of the stadium was ongoing and the police used dogs. After the controlled explosion it was found that the package was a training device accidentally left by a private company following a training exercise involving explosive search dogs. So “this device was as real as could be and the decision to evacuate the stadium was the right thing to do, until we could be sure that people were not at risk,” the club released. The operation proved already the people remained calm and moved quickly on the safe zone. “The Premier League will seek to rearrange the fixture as soon as practically possible and will advise fans accordingly,” an announcement was made.
