premise: BAGNERES DE-LUCHON, France (AP) — Four-time champion Chris Froome is among several riders who have had their eyes treated for tear gas or pepper spray sprayed on the peloton when a farmer’s protest interrupted the 16th stage of the Tour de France. Police had to remove bales of hay blocking the road 30 kilometers into the 218-kilometer leg from Carcassonne to Bagneres De-Luchon. An Associated Press photographer at the scene says Froome and other riders had eye drops applied while stopped for several minutes. It isn’t immediately clear who used the chemicals.
hypothesis: It is not clear if the farmers used chemicals on Froome.
reason: The text clearly says the police were not sure who used the chemicals. The text may have not been clear enough for the system to understand that the chemicals referred to tear gas or pepper spray.
