Patlabor: The New Files - Season 1 Episode 6 Black Trinary

After the hot water system (a 40-gallon drum attached to propane tank) at the SV2 literally blows up, Division 2 is forced to go to a bath house to wash themselves. Upon driving to the bath house, they come across a man lying unconscious in the street. He identifies himself as a policeman. He has been tracking down a terrorist who has been responsible for several bombings of businesses with contracts with the Babylon Project. He found the terrorist, but was knocked out by him before he could be arrested. Before the police officer passes out, he tells them the terrorist can be identified by three moles under his right arm. None of the team saw anybody pass the van they were driving in, so he must have headed in the other direction: a dead-end street with the bath house at the end of it. The men of Division 2 decide to arrest the culprit and enter the bath house. The only problem is that most of the suspects look like Yakuza members, and who in their right mind would attempt to look under their armpits?
