Members of the bomb disposal squad (DOVO) had to try and approach the man to find out whether or not he was wearing explosives. At least, that was the plan. As the man behaved suspiciously, a robot was sent to the spot, revealing that the suspect was wearing metal plaques.

Eventually, the suspect turned out to be an innocent student who was wearing something that looked like a belt - including some wires - to do research about radiation and air waves in Brussels, Christian De Coninck of the Brussels police told a press conference.

"When we found out his body was covered with metal plaques and considering the fact he did not cooperate, we had to step up our efforts", he explained the massive operation.

It's possible the student will have to cover the cost of the operation. "Given the fact that the person was behaving very passively and suspiciously during the operation, police will file a claim for financial compensation". The man was taken in for questioning.
