Police in Amsterdam are investigating whether criminals caused an explosion at an apartment building that injured seven people and forced 400 residents to evacuate.
Three people have been detained, police said on Saturday. After an extensive rescue operation, officials now believe there are no more victims trapped beneath the rubble.
The powerful blast occurred in an annex attached to the apartment building in the early hours of Friday. The explosion triggered a major fire and caused part of the structure to collapse, the police statement said.
