GRAPHIC WARNING: Russian roulette shock as wedding guest shoots himself in party trick gone wrong

(U.K. Mail Online) - A wedding guest was arrested by police after a man was seriously wounded playing 'Russian roulette' in front of a horrified bride and groom.

The guest had been giving a toast when he pretended he was playing the deadly game with a gun that he claimed he thought was entirely empty.

But then he gave the gun to another guest - and it turned out that he had been tragically wrong.

The second guest also fired the handgun against his head - and dropped to ground as a rubber bullet exploded into his skull.

The first guest can be seen standing in shock for a split second after the shot is fired.
