Riot control measure (4,3)

I believe the answer is:

tear gas

(Other definitions for tear gas that I've seen before include "It causes temporary blindness" , "Discharge sprayed by riot police" , "Crowd disperser" , "Riot control weapon" , "Airlike substance that irritates the eyes, used in riots" .)

I've seen this clue in The Sun.
