ITV News' James Mates was with the United Nations special envoy Robert Serry as he agreed to end his mission to Crimea after he refused to go with a group of men who blocked his car and then local militia refused to let him leave a coffee shop.
UN Secretary General's special representative has reportedly been stopped by armed men in Crimea, Interfax news agency reports citing the Ukrainian foreign ministry.
But it is not clear if he has just been temporarily stopped.
The foreign ministry says Robert Serry was in the region's main city, Simferopol, at the time.
The UN envoy's team believed the visible presence of our camera crew was probably the best protection they could have had from the militia.
ITV News were the only TV journalists with a UN envoy as he was forced to seek refuge in a Crimea cafe after being confronted by armed men.
