Saudi police in the capital Riyadh said they had arrested a man, who appeared in a video shooting in the air while he was carrying a newborn.
The viral clip showed a muslim man firing in celebration while the baby was crying.
Another man can be heard urging the shooter to make the baby smell the gun powder.
A clip in the video shows one of the two men, whose faces were not seen, put the muzzle of the gun in the baby’s mouth.
It is unclear why the gun was placed in the baby’s mouth.
