The Dutch police seized a number of MH17 related items, including possible human remains, from freelance reporter Michel Spekkers at Schiphol airport on Saturday night. The reporter was returning from a trip to the Ukraine, where he visited the MH17 crash site, news wire AFP reports.

In a statement on Sunday, the Public Prosecutor said that "various bags with metal parts and an object which my be human remains" will be examined as soon as possible. The Prosecutor also said that Spekkers "refused to hand over photographic and film material from the crash site".

Spekkers responded on Twitter by saying that he arranged to voluntarily give up the items he found, but that his encounter with the police ended in a "total seizure" of his possessions. 

The reporter was visiting Donetsk to make a documentary about daily life there, he wrote in Noordhollands Dagblad. He decided to visit the MH17 crash site after hearing stories about debris still strewn in the area. According to him, he found various things lying around, including a piece of bone. Seeing so much debris still at the crash site left him with "an uncomfortable feeling of helplessness", he wrote.

Spekkers filmed everything he saw. He decided to bring back some items, hoping that they may bring :some answers to outstanding questions".
