An Iranian man has been caught on film threatening to shove a tear gas canister down a woman's throat for refusing to wear a headscarf.
In the footage the man can be seen approaching the woman with the canister in his hand while other people try to stop him.
The woman can be heard asking him what he's doing with the canister before he responds: 'Yes, I'm going to shove tear gas down your throat.
'Then you won't be able to speak for two days.'
