A 22-year-old British tourist was arrested in Malaga on Sunday after spitting at police officers when they told him to put on his face mask.
The man, who was approached while drinking alcohol on the seafront promenade near the Malagueta beach, was with two friends who both followed the officers' instructions.
Despite being asked to put on a mask five times in English, he continued to refuse, becoming aggressive with officers and spitting at them.
He was arrested, but became so agitated that he was taken to hospital where he was restrained and sedated.
According to his sister and girlfriend, who provided his passport so he could be identified, he had not taken drugs, but had drunk a lot.
They also said that bouts of aggression were not unusual for him.
